Algodoo

Just a try to recreate smth similar to Roots vacuum pump.

Controls:
Arrows Up - delete circles
Right - spawn circles
Down - invert direction (hold)
Left - brakes (toggle)

It's pretty crude old scene, which I abadoned long ago.
I'd improved scene, but it still be crude and alike "in alpha".
I'd changed blades on actually Roots profile and rebuild chamber.
And decided to share it.

I tho for someone it will be interesting.. as visualization model.
Anyway better than abadoned with unfinished projects.
