Yes, he is Polish.
YAY he is slavic!
He gets on IRC every so often. He did create the original powder toy. You can download it at geeks 3D, and he came up with the powder toy because he got idea from DanBall's Powder Game aka DUST. Then a little lad named @Simon came along and Skylark (Stanislaw K. Skowronek), gave him the code. Than Simon made it the best physics game ever. The Powder Toy was first created in August of 2008.
