PLEASE NOTE: Numberphile is not associated with Karl's project and does not benefit from it. He sent us the sculptures without warning or promise of publicity... We just liked it and wanted to support a great numbery idea.
Also note we do not vouch for Karl's product. In fact, the model sent to Brady has fallen out of sync on a couple of occasions and required re-calibration (using the instructions supplied by Karl with each model)... But we still think it's great and have had fun with it! Thanks Karl.
