Google Cardboard

I tried out google's cardboard virtual reality (VR) system this week. It was awesome!

I have always been a big google fanboy, mostly because they make life cheaper and easier. And most of their applications are free. What is to really be admired though is their commitment to lateral thinking and cool science. For the uninformed, google cardboard is one such project. A couple of google employees took some time out to write an application that ports google maps, photos and youtube to a stereo display format on supported android devices. They then designed a simple cardboard mount to hold the phone to be viewed through lenses on the mount. They even put a cute little magnet contraption on the side of the mount to act as a switch detected by the phone. And then they released the app and the mount schematics for free. 

I had heard of some upcoming sophisticated VR devices that are apparently poised to take humanity a lot closer to The Matrix. So when google announced this cheap cardboard app, I wanted to try it out. I was skeptical however. You see, most of my specialized viewing experiences have been less fun than expected. Stereo images make my eyes water and 3D movies give me a headache. I still grieve the day I spent $17 on a that awful remake of Clash of the Titans (in 3D!) that looked better without the glasses. I spent a weekend playing Super Mario 3D land on the 3DS console and it was OK because I turned off the 3D function. But a gadget-geek coworker encouraged me to try it out just as a craft project, so I bought in. The schematics were simple enough and in no time I had the pieces ready. Getting the lenses was a little tricky but I managed to find what I needed ($2.52) from the local hipster hardware store. I had a couple of spare magnets lying around for the switch contraption.


Assembly was a breeze and I had the mount ready in ten minutes. The phone app was quite big and I was concerned if my faithful old galaxy nexus would handle the beast but it loaded fine. 


I turned on the app and a playstation-like menu popped up and I could navigate through it by looking around. The dual viewing paired with the lenses worked well enough and I could see just one image; the measurements from the schematics weren't too shabby. I magnet-contraption-clicked on the street view (street vue) option and within seconds my mind was blown. 

It put me on a car driving through a European city in full speed where I was free to look around and it rocked! I am a big google maps user and I spend about half hour everyday taking virtual tours through the world on it. This was that experience on steroids. I spent a good ten minutes on the ride after which I tried the other options, that were mercifully slower paced. The earth option puts you on a stationary spot in a few selected locations and surrounds you with google's 3D building models to look at. You can even fly off to space and look at the earth from above. Tour guide does the same with some select spots in Versailles and adds voiced descriptions. Photosphere allows you to explore you own photosphere images. While all these options were more like trial versions than full fledged virtual worlds, the youtube app seemed more open. It put you in a theater-like surrounding with the video of choice running on the big screen and more videos on the side to look at and click on. Some of the videos seemed related to my viewing history on youtube, so I suspect that it may have a longer lifetime than the other app options. 

It was a fun home project. Overall, the experience was brilliant cheap fun and has me lauding the google engineers that came up with it for their smart work. Thumbs up gentlemen, keep up the good work!

Cedar Bluffs

There are a good number of established trails and state parks around south-west Indiana. Cedar Bluffs remains one of the less discovered locations. I like trails that are less manufactured and more rugged and Cedar Bluffs gets a 8/10 for that. It is lush green, has water bodies, plenty of small creatures and hardly any noise.


It was a nice warm day and we drove south along S Ketcham Rd until we saw a tiny black board marking the entrance to Cedar Bluffs. It is basically a protected nature preserve and you are cautioned to not go off trail and ruin its delicate fauna. 

Ramya had been there before so she was to guide me through the trail. 

The trail started out pretty and innocuous. I let Ramya lead our party and used my camera to cover the walk in google glass-like fashion.


We walked until we hit the stream that goes along the trail. A number of people seem to come here for fishing.

 






On the other side of the trail was this rocky cliff that we had to get to later. 

At one point the trail turned to the left but we decided that we knew better and ended up making our own trail. That is when the fun started.


The trail got a lot less trail-like and we had to now find a way to get to the cliffs from there. So we turned left and headed uphill. 


The place was now a maze of spiderwebs and trees. Note: You will have to leave your arachnophobia at home to come here.

Lost. Yes.


No we were totally off.

After unwillingly and unintentionally destroying a dozen spider homes, we compass-ed our way back to the true trail and we decided to stick to it from that point on. 

Win. And we learnt something.

The trail is actually a smaller stream that joined the one we walked along.

Trail 

Not trail

A little farther on, Ramya found some parts of the trail that she actually remembered!


Like Ariel's grotto but with snakes.

We stayed along the trail until we could get back on the hillock we had seen and walked down the other side of it back to our car. Overall a pretty fun place. I recommend it.

Crapstallography

I spend a good amount of time at work wading through microscopy images of concentrated proteins soaking in salt syrups that should hopefully tease them into forming innocent pretty crystals (that I can mercilessly shot with X-ray guns but that part is another story). It takes just a glance to figure an image out. So with a few thousand conditions and a few images per condition the whole process takes just a few thousand times a few glaces.

Rarely do you get to see something that has crystal written across the image with zoom-in zoom-out effects. The image on the right is a UV light image of the same drop.


Less rarely, you get to see misshapen gunk that has meh written across the image with sound effects that say 'really'?


Then you can spend some time perfecting the syrup recipe until you have something that is workable.


What you see most of the time is either clear boring drops or drops that contain what looks like shredded snakes or alien foetuses.


This one actually looks like the alien from alien.


An that is the scary part. You wade through enough of these crap-drop images that you start seeing mind-game things. Like smiley faces.




Or flirty botched plastic surgery-lips.


Or hand-bags.




Spend enough time and you really start seeing crazy things. Like stars.





Or the Batman.


Must...focus...



I am headed out for some soup, sports and grounded sanity. Peace.
