I have indeed
I love the Experimental Gameplay Project site - it's got loads of cool stuff you don't find in the mainstream games market, but the community seems a little dead now and I'm a bit reluctant to upload my own stuff because their TOS and submission policy pages are broken links.
Anyway, I spent hours trying to work out how Tower of Goo works (and building highly unstable towers)! Kyle Gabler is certainly talented, and I definately look forward to seeing more games from him in the future
