Cas's first product, Geemo is a flexible toy with magnetic limbs that attract and repel each other in unpredictable ways. Inspired by patterns in nature, Cas was interested in designing units that would form irregular patterns and join together into larger units. The magnetic limbs were left unmarked and uncolored because Cas felt there was something wonderful about not knowing whether any two limbs would attract or repel until you try.

Geemo was invented while Cas was pursuing her MFA at Cranbrook and launched at the NY MoMA Design Store in 2007. It has since won numerous awards and been shown in design and toy fairs in Moscow, Tokyo, Seoul, New York, Hamburg and Riyadh, Saudi Arabia.
