I hate Farmville.
So last weekend I set myself the challenge of seeing what I could do with the Facebook APIs, and the following video presents the outcome.
I'm pretty busy this weekend, but I plan on getting at the very least a photo gallery viewer for all my friends.
Currently I'm targeting Qt for the prototype as I'm initially tailoring it as a Desktop Windows/Mac prototype. However as the codebase is based off OpenGL, I have got it running on iPhone and Android.
If you're interested in this project, let me know and I'll be happy to give you an early release.
