Yeah, do ya get it
Anyway's, as you just discovered somebody jumped the gun on your idea, I had a similar experience.
I fantasised about creating a single wheel motorcycle. The type where you sit inside the wheel. Imagine my disgust when I happened upon it on the net, not as an idea but a fully worked up prototype.
Here's my "get it" analogy. If I loan my neighbour my hedge trimmer he/she's unlikely to clone it.
