Solar Powered Flowers

Here are a few solar powered flowers that I've been working on with my business partner (he's the engineer). The flowers charge up a battery at night using inlaid photovoltaic cells and release this charge at night by illuminating themselves with internal LED's. We've got a web site and a facebook page now as well :
