I do, but it's currently not on Tapastic!
Dreamspace is all gifs. Flashy, eye-gouging gifs for the most part, so proceed at your own risk :V (also every part is 10-15mb worth of gifs, might take a few minutes to load depending on your connection)
I've got some random gifs on one of my Tapastic comics, too and I'm thinking of integrating more animation into the main comic of Drugs & Wires soon.
The other one I can think of that uses gifs on Tapastic is Brain Damage, though it's not it's main thing.
And if you're up for some comic with Flash animation for inspiration, Buying Time (18+) and Nawlz are amazing interactive works.
And I guess Homestuck kind of goes without saying? Everybody knows it, right? : D
