Semi serious: was that enough to have patented the idea yourself?

I believe you can get patents without a physical model?

I wouldn't have bothered with a patent for something like this though. Probably is money in it now I think about it, but patents are just not the kind of thing I think much about.

You can get a patent for something that doesn't even have to necessarily work.
