I've been coding for very long, and I've noticed that many people think that they're not smart enough to learn how to program. Those who do believe in themselves seek challenges, but then get bogged down by complexity. Tickle is my solution. With Tickle, users learn the concepts of programming with block-based programming on a computer where they are the ones who need to make the apps. This is in a way similar to the beginnings of computers, where users needed to write their own programs in order to use a computer. But now, most computer users are basically only consumers, using the things that other people create. The goal of Tickle is to bring learning and creativity back to using a computer.
