Kris Kras (@stduio, 2013) is a double random walk on a grid of 1024 violin sounds. The black walk ends in the lower right corner, when the 1024^th sound is played. The white walk ends in the upper left corner, when the 1^st sound is played . When both black and white are walking, playing will stop when they meet, i.e. when the two flaneurs hit upon the same sound at (approximately) the same time.
Kris Kras is one among a myriad of possible variations on the theme set by the ookoi's 1024. Read more in 'How to keep devils away'.

(Kris Kras was composed @stduio from a pack of 246 single tone violin samples, recorded and made available by ldk1609 @ freesound.org)
