"Mad pixels" is an application that shows what effects can be achieved using only ordinary squares. In the application we have access to several modes, each of which allows you to select the number and size of "pixels". Random mode showing the chaos in its pure form, fractal mode, in which "pixels" move according to fixed patterns, 'Arkanoid' mode, slightly referring to the principles of this famous game. Moreover, in benchmark mode, we can see how many "pixels" our device is able to show at the same time.
