I remember seeing a site a while ago, but I didn’t bookmark it (slaps self again), can’t remember what it was called, who made it, how I found it, basically I remember nothing that will help me find it again. All I do know is that it was quite simple, I think it was black on white background, and you controlled a man with the arrow keys to navigate this virtual world, and when you bumped into things they animated for a short while. He grew wings and flew when you pressed up. If anyone can guess what site I’m thinking of by that poor description, I will be very impressed and grateful.
EDIT: It’s very much like this site, but simpler and cleaner - http://www.josefigueiredo.com/
