I'm actually recommending the whole website. The linked course is what convinced me to share it. It's a very neat idea for visualising arithmetics and calculations done in an original way. Or at least one that I didn't see used before.

Perhaps it would be a good thing to use in a classroom or to teach kids who are struggling with basic maths? I'm actually wondering about making it into interactive 'app'.
