Listen up, puzzle lovers. I've got a site you're going to love.

Today's site features Tangrams, old Chinese puzzles.
You've probably seen them before, even if the name
doesn't sound familiar.

You're presented with a series of geometric shapes –
squares, polygons and triangles. The goal is to fit
them together into different shapes.

It sounds easy, but it can be quite a challenge. If
you get stuck, use the cheat option.

By the way, this is a great site for children. It will
help them with spatial relations. In other words, it
will make them smarty-pants.
