This is a heavily customized Sunflower Power Plant kit from the infamous Craig Maynard. I opted to make it into a head configuration instead of the standard floral arrangement. This solar head arrangement tracks light extremely well and has a twitchy movement that is very active and life like. In fact, I would say it tracks light better than any other head I've built. This may be due to the use of IR detectors as eyes rather than the more common photodiodes or CDS cells. This kit, like all of Craig's kits, is very high quality and easy to build and understand. I highly recommend it in either mechanical arrangement. You can purchase one, or any of Craig's other kits, at Craig's Cybug web site.
