(crappy) Piston Valve Animation

[Rudesill Ballistics]

Your animation isn't pretty, but it appears to be accurate to the function of a piston valve.

You've chosen an easy to "read" color scheme for it too.

Did you use flash to make that? I use flash as well, hard to get use to and lots of dicking around, but even though it doesn't look nice it still gets out the basic point, and they're fun to make when bored...All most as fun as photo-shopping celeb's face's onto other people's head's

I used some demo of Zoner 5 something or other.

Believe me though, I put barely any effort into this. I was just screwing around seeing how it worked. As far as I know, you can only paint to edit frames and right there you know it's limited. My paint skills are far better but again- NO effort here
