This day and age people tend to get easily low on their morale for every little reason. I wanted to help them quickly recharge themselves with some great quotes that inspires and boost them up, most of the time.

In that process I'm working on my iOS app Quotegram, which is now available in the AppStore. It's one of the best looking apps on the Quotes niche on the AppStore.

It's cool because practically it has helped me recharge myself in a couple instances in the recent past and I'm sure it would help those in need of a quick recharge.

Laser projection. https://www.youtube.com/watch?v=x034jVB1avs (Pong on a 20 story building, billboards, etc.) http://www.youtube.com/watch?v=5S5_v2By3Ec (Multiple laser projectors) http://www.youtube.com/watch?v=2m-A9LvPbmg (Canny edge detector) http://www.youtube.com/watch?v=5XTi-jf-ans (Asteroids on a 4 story building) http://www.youtube.com/watch?v=uF_OCvjq3ps (Reddit's Snoo on a 20 story building) I've just added…

Curious, are there any safety implications? What happens if the light shines directly into someone's eyes? Like if you projected on a building and the laser light went through a window and hit someone in the eye.

CameraLends ( https://www.cameralends.com ) -- AirBnB for cameras, rent cameras and lenses from local photographers. It's cool because: - sharing feels good - if you have camera gear, you're probably not using it all the time - it's a way earn back cash from lending out gear - it's a side project that I've bootstrapped this year :)

I like your idea, I was thinking about it other day. I am working on my private pilot license and in a month or so, I will be doing my first solo. I want to record it but then I don't want to spend too much buying a new goPro. It would be nice, if I could rent it for few days for fraction of cost. I am sure there is a market for it.

Hi imtu80! We already have GoPros in the San Francisco market (which is this one we're actively growing). Feel free to email me (adam at cameralends.com) if you have any other feedback!

Cool! I was experimenting on something similar with BeagleBoneBlack and libVLC. However, the 3.8 kernel doesn't have drivers for onboard SGX GPU; and I couldn't get decent resolution with software decoding. Are you using OMX libs on Pi? With hardware decoding?

Yes - I decode a raw stream in a thread using OMX. I don't need sound so I don't have to worry about a demux library, it's just a raw H264 stream I hand off to the hardware.

Thanks! By the way, somebody managed to get hardware acceleration working for VLC on Raspberry Pi. So, now we've two options: OMX or VLC.

Thank you - definitely something to try when I have more time to experiment. I should move my C up a gear, grab the mplayer source and write a Pi driver for it as well.
