The moment leap motion came out, I was amazed by the prospect of new input methods into computers. From the amazing videos I gathered many ideas for all sorts of projects I could try.
Consequently, I applied for a developer pre-release kit.
Upon first impressions, I really liked the product. However struggled with some of the poor precision that could be achieved due to the software becoming confused about which fingers it was dealing with at the time. I must stress this was an early development kit, before general sale and so I assume some of these problems have been addressed by now. As a result, I went for a simple yet fun virtual steering wheel project which more information can be read here.
