Seven origami cranes in steel stand ten feet in the air. Lit with LED spotlights and animated LED strips, Nozomi invites the public to wander at night among colorful, brightly lit, whimsical shapes. Nozomi was funded by Ignition Northwest and donations from the community and was shown at Burning Man and Critical Northwest 2012.
I designed and fabricated spot lights featuring a high power LED driven by a constant current source for power efficiency. Spotlights were chosen for several cranes to highlight stark arrangements of geometric shapes or monotone covering material.

A series of nested concentric rings mounted on independent bearings allows participants to spin the rings in all directions. Ablation Cascade seeks to evoke the orbits of satellites and remind us of the unseen space debris high above. Ablation Cascade was funded by Ignition Northwest and donations from the community and was shown at Burning Man and Critical Northwest 2013.
Designed to be a gathering space offering shade and a view by day and contributing to the lit skyline by night with its animated electroluminescent lighting effects. Arborealis was funded by Ignition Northwest and donations from the community and was shown at Burning Man and Critical Northwest 2010.
