Leopard (not to be confused with the Apple OS) is a really interesting program language for kids developed by Brandon Watts. It uses extremely simple methods to create highly complex programs, very useful for teaching the basics of programming to kids (or anyone else who wants to learn programming, for that matter).
Brandon partnered with Weatherbug several years ago, where Weatherbug offered a co-branded version of the development program for use by kids.
The partnership with Weatherbug is now at an end, and Brandon is looking for a new home for the program. If you have any ideas, feel free to contact Brandon.
