This was Zelda the art mouse's knitting machine. I geared her wheel down, so when she ran she powered a little knitting mill. Her life’s work was one wool scarf, and it took her six months to complete.

Zelda’s scarf was a given as a gift to my grandmother.

This is a playful machine I built for a preschool in Berkeley, California. The machine uses ramps and conveyor belts to create a river of pompoms for the children to play with.

The tiltshift-o-scope is a special telescope that makes the world look like a little toy model of itself. 

It uses a very large lens to project an image onto a tilted glass screen. Because the screen is tilted, only one part of the image is in focus, and everything else gets blurry. 

This simulates a shallow depth of field, and everything you look at seems tiny!

The Tilt-o-scope was displayed at the Peabody Essex Museum in Salem, Massachusetts as part of the Sizing It Up: Scale and Nature in Art exhibition. 

This card is a tiny paper camera obscura! 

When you place it next to the candle, pinhole images of the candle flame appear to light the candles on the little cake. 

There are several little pinholes on the front of the card, and light from the candle flame passes through the little pinholes to project inverted images of the candle flames onto the little painted cake. If you blow out the candle, the ones on the cake go out, too!
