What resolution were you in?
Well, first of all, you should really consider saving projects. I know, they can get big, but you can always toss them out later. Such a black image would indicate that you likely ran out of memory, potentially because some other app was using GL at the same time or any graphics memory or you might've had more layers than your computer can handle?!

...something of that kind. You do, of course, have some really challenging circumstances at the moment. I'm very sorry about that.
However, very interesting texture there. I was going to say "bumble bee in the middle of a crash sequence?!", hehe, but don't want to take away from the impression. With such small resolutions it's hard to take in the full effect, I think. Still...keep 'em coming!
