Hypotrochoid Art Set
$9.99
Turn math into art. Classic Hypotrochoid Art Set traces out hypotrochoid and epitrochoid curves turning math into beautiful art. It's easy and fun -- a hypotrochoid is a roulette traced by a point attached to a circle of radius r rolling around the inside of a fixed circle of radius R, where the point is a distance d from the center of the interior circle.

Classic Mini Mandala
$9.99
This is a great product for making your own mandalas. The stencils are great and it's easy to use. My only complaints would be that the stencil is not completley tight in the circle that holds it which can lead to circles that don't always line up at their completion - with practice this can be cvercome. Also the colored pencils they give are too few and there is not pencil sharpener included. All of that said, I love this product and have had a blast creating beautiful mandalas. I have the classic size one also and actually prefer the mini.
