Python Playground (No Starch Press, USA) is the culmination of a few years of playing around with Python, plus 2 years of writing (ouch!).

It's a playful romp through Python - 14 projects ranging from drawing spirographs using Turtle and parametric equations, to creating Particle systems in OpenGL, to creating a laser audio show using Arduino, FFT and Python.
