Interaction/industrial designer Matt Brown has come up with something really random and fun here. It's a self-slicing pizza. Instead of using one unbroken round of dough, Brown has cut up the dough into pieces and then worked them together in various overlapping patterns so that when you grab a "slice," the pizza decides how large (or small) it will be. It all depends on how the
tessellated pieces were arranged with their neighboring bits.
This was Brown's first self-slicing pizza experiment. He says he'll toy with different patterns to see how it affects the pull-apart experience.
