andries odendaal, now famous for his isometric conjurings in flash, has developed one of the best flash games i've seen in ages: WhizzBall! play it here:

in WhizzBall, you have to figure out how to roll a ball from point A to point B by placing tubes, jumps, teleports, etc around the playing surface. trick is, you can only use the specific pieces provided for each level. you even get to create and publish your own levels! last i checked there were 20, 000 levels. OMG! congrats andries...it's a work of art.
