I'm a pretty digital guy. I like most of my creations to have very low per-unit construction, storage, and distribution costs, or at the very least be digitally sourced (oh nostalgia).
I do love carpentry and electronics though, so here are some creations with more significant real-world presence than most.
For Christmas 2004 I made my parents a lamp-object.
For Christmas 2006 I made my parents a mobile-object.
