When I wonder if the time I spend on my projects is worthwhile it's great to read about daft/strange/incredible things that others are doing.
Here's a couple -
The Toaster Project - hey the electric toaster is 100!!!
Maybe the end result will have a retro look - how about these? 1920s Toasters
See the Toaster Museum at http://www.toaster.org/
The Impossible Project - "shake it like a Polaroid picture"
