[Jared] sent us a feature he posted involving time-lapse photography and an LED. Using a custom built aparatus an LED is moved on two axis’ during a long exposure of around thirty seconds. The frame is wood and PVC with two gearhead motors powered by AA batteries to provide the locomotion. The LED is powered by a 3v button cell and automatically transitions through different colors.
A similar project was posted on Make with KNEX

It’s really not time lapse
This one is pretty simple but can easily expand into a more powerful hack. He could (for example) create a computer simulator that given the motors speed, create a pre-visualization of what the long exposure image would be.
@Drew G
Indeed
I’d like to see leds on the double square pendulum: http://www.youtube.com/watch?v=cXRXWy5KMgs
Not really time-lapse. More long-exposure photography.
The plural of axis is “axes”.
As a general rule for difficult words, using an apostrophe in a plural is always wrong.
