I promised Jimmy I’d try not to distract him with computer games that would appeal to him while he’s revising. It turns out I lied.
I’ve just discovered Plasma Pong. It’s like Pong – you know, two paddles, a ball, that whole lark – except it mixes the genre up with some of the fastest computer models of two-dimensional fluid dynamics to put a completely new twist on things. The paddles and the ball are in a tank of coloured fluids, in which ripples can be created (by, for example, the movements of the paddles and the ball). Better yet, by holding one or the other mouse button, the player can "inject" fluid into the arena, suck it out into a vacuum, or blast a shockwave out. It starts pretty tame, with players trying to "push" the ball past one another, but as ripples and currents begin to appear, players have to work fast to manipulate the ball to get it past their opponent.
