If you enjoy generative graphic design, you may just like Büro Destruct's just released "Designer" app for the iPhone and iPod/Touch. Shake your iPhone to create a virtually infinite number of visual designs. Using only circles, squares and a set of rules, Büro Destruct Designer aims to find you inspiration from color combinations and graphic shapes. Choose either full random colors or apply rules to your color palettes. You can modify your compositions with gestures and the various tools from the menu. Especially neat feature is the ability to save the results and share them by e-mail including the color ref palette.
