Some big players include; PPP, DCUA
Universities in the game; Carnegie Mellon University, New York University etc.
U of T? That's our point!

Hey look it's a cute cat! Uhh... really? Look harder
We hope this seminar inspired you!
We can't teach you everything. For those of you interested, you'll have to learn a lot on your own!
