"If you have another way to donate in mind"
Seems like this would be an ideal project for a kickstarter, that way at least the project could create a more informative project page and detail exactly how they hope to spend the money with perhaps the goal of building a prototype in a given time-scale.At the moment it looks a bit too much like someone's had a great idea, done a bit of initial design and thrown together a wiki page. It doesn't seem serious enough for me to donate at this stage.
