knikkertijd
Knikkertijd is dutch for ‘marbletime’: a few times a year there would be a period of a few days/weeks that the main game played at the schoolyard was marbles.
This flash 8 application used two displacement maps per marble: one for the underground, and one (mod width) for the glass swirl inside the marble. I do plan to put some more gaming elements in there, but for now just go knikkeren.
