The inventor's patent contains no moving parts, is constructed from a single piece of plastic, and is supported by a single finger when spinning. While it might be an entertaining toy, it's a completely different product.
Regarding the inventor's fundraising campaign, I think the Kickstarter platform is a poor choice given the circumstances. The current campaign is very poorly written, and gives a potential backer no confidence that the product would ever see the light of day.
A different platform without the "all or nothing" constraint would have been a better choice, and the campaign would be better structured as a direct appeal to charity. The inventor is obviously dealing with some difficult personal issues, and a flat sum of money --without the strings of a demanding production schedule attached-- would likely be far more beneficial.
