Yes, I think about it all the time. It's not very often that I don't have one or three crazy ideas about a short video popping in my head.
Problem is that I do FX work for other filmmakers so much now, that I want to escape from my machine more often than I want to work on my own stuff these days.
But, when I get time, I plan to... um plan on making some more FX shorts. LOL!
For what it's worth MO, it's not a matter of if, it's when.
Right now, between my paying work, I'm putting together a new demo for the coming "Indie" meet in Las Vegas this May.
