Recently I stumbled upon WebRTC. I started looking into this and found some useful libraries on github .

I have been creating some games in Javascript so thought why not use one of these libraries to use some gestures to play a game .

Brainturk.com is yet another perl powered app that I have been working on , These games are taken from various research papers and articles published. Try it out and let me know if you have any comments/suggestions

Interesting to see the function call
objdump -D /usr/bin/perl |grep -A400 main.: |grep call

to get the output in intel syntax add the option -M

objdump -M intel ...

GDB

Gabor has a post here where he points out that the level of interaction is lower than the other blogs, he mentions blogs.perl.org and chromatic's blog as an example.
On more than one occasion I have typed in my comment only to realize that you need to be logged in to comment ( Gabor's , blogs.perl.org and chromatic's blog all require login) . I understand spam is a issue but if you want me to login to comment I will most probably not do it .
