This one blew me away. I stumbled across a fantastic remake of the classic pong game. Modified to take into consideration real time fluid dynamics of course. A stunning blend of colours splays across the screen in all its chaotic glory.
You can play in either one or two player mode. In one player mode simply control the paddle with the mouse, using the left and right buttons to suck or pull the fluid. When you hold the right one in it suctions then dissipates, allowing you to capture then fling the ball out.
I played a game then tweaked a few settings. Set it to run in maximum monitor resolution, and clicked some speed up options for the ball. I scored 25 for game two. It was psychedelic mayhem.
I think I may try to get this going for at a party. Can you just imagine it?
