Can machines do art?

Mine can!

We built a machine that can rotate around two axles at the same time.  

A glass surface is attached to the machine by one of the two axles.

Its movements can be traced with a marker that's held by a lego arm.

...repeat the process and you get these amazing shapes... not two of them are
alike!!

My dad and I built a lego machine with gears, that turns around with

 4 tiny flashlights on it.  It works  kind of like a carousel.

We turned the machine on and I made some photos.  The twirling movement of the lights created these amazing shapes. 

The following photo shows the machine turned off, but the lights on.
