I am a Visual Arts - Media major with an interest in graphic design. I was born in Europe, and moved to Canada when I was 5. I've lived in San Diego since I was 10, and graduated from University City High School before coming to UCSD as a transfer. I have been working with computers since grade school, and am highly interested in pursuing a career in the computer field. I have been in interested in electronics also since a young age and I think it will add an interesting dimension to my artistic career, and am eagerly looking forward to learning how to make art projects using them.

== Midterm Proposal ==
My proposal is a hat which contains a cooling fan enabled by a switch. The switch will hang down from the inside of the hat to about shoulder length, enabling the wearer to turn on and off the fan. This is a crude implementation of a warm weather cowboy hat which provides cooling apart from shade. It will be powered by a 9v battery, and connected by a normally open switch. In order to operate the fan, you must hold down the button.

== Final Proposal ==
My final project will be called "Punch a Celebrity". It will consist of a punching pad with a picture of a celebrity on it. The pad will have an impact sensor attached to a arduino/breakout board, which is attached to a speaker. This will enable a wav or mp3 file to play at the moment of impact, and simulate that you are actually hitting a celebrity.
