I signed up for a free on-line class at corsera.org called “Design:Creation of Artifacts in Society. Every week there is a prompt to do a little design problem, this week they asked everyone to identify some sort of thing we found dissatisfying in our environments, and come up with a solution. I found there where no really good looking cat for sale at petsmart so I decided to design a better looking, better smelling cat box.

The cat box doubles as a planter to help make it less obvious that it is a cat box. Coming out of the top of the cat box are tubes filled with activated charcoal connect to the litter chamber that help ventilate the cat box while eliminating odor. There are also solid Pyrex tubes sticking out of the top of the box to help channel light in to the litter compartment, similar to they system used in the scjohnson building by Frank Loyd Wright http://scjohnson.com/en/company/architecture/Wright-Buildings.aspx. I ran out of  time to finish this they way I wanted to before it was due, but you get the idea.
