Well, I could tell you about it but then...
All I can say is that during my sabbatical I had some ideas dependent on some technology developments which I read about (you have lots of time to read far and wide on the internet with Scroogle when you are at home all day without having to worry about your boss looking over your shoulder).
I have some concepts but I need to see how the technology pans out and work out the details that I'd need to use it. Then I'd need to get it all documented, dated and patent applications underway, etc., before I could start looking to fund it.
So for now, like the schools initiative, it'll have to sit on the back burner.
