And now for something completely different is the "Ravioli" Laser Painter. In summary, a laser pointer is fitted to a tilt/pan head controlled by two servos via an Arduino. The laser beam is then controlled to draw words on a wall. The text to display comes from a PC running a Python script. Furthermore the Arduino also controls the exposure time of a digital camera - when set to a long time, it can capture the entire writing of the laser pointer. For example:
This is a very inventive project and would be a lot of fun to make party or event souvenirs, or just as another form of random interactive art.
