hi,
In the past i had an exibit in my job with a aluminium bar with a lot of electronic components. The only visible componentes was a sequence of red leds (about 40 or 50). The leds blinkin without a logical order when the bar is stopped. But when somebody move the bar very fast, we'll see a perfect image of a scull(is the retinal persistence fenomenal), but can be another image.
Somebody broken the bar and the electronic circuit a few years ago, and i need to create a new one. We don't have the bar...
Can you heep us?
Thanks!
