just found this very cool ps3 game called echochrome downloadable from psn. Its all to do with perspective and is very escher like

demo is free, full game is about £6

addictive and very challenging, well for me anyway

demo linky

Yeh i got the demo too and find it good fun. I also recomend 'monsters' which is about a year old now. Spent hours on this game which is simple but hard to get right.

i think you can get the first game on the PSP also so might download it for my holiday.
