I stumbled across this new project called Salasaga
I haven't downloaded it yet, but it looks like a nice project. It's still brand new and buggy (according to the site) but what does everyone think?
I'd heard it'd be nearly impossible to create something like Macromedia Flash to use on linux because they're so "closed source". I hope they can make it work. Macromedia is the only thing keeping me from dropping Windows completely.
