I stumbled upon this site the other day and thought it was well worth a mention here; even if the gadgets are a little low tech. Flying Pig produces paper animation kits that you can download and print from your home computer. Once printed you just need to follow the instructions to produce your very own low tech paper animated gadgets.
The site has several different animated paper models that can be downloaded for a small price (and some available for free). These would make great stocking fillers or gifts for those that have everything.
Check the site out and see what you think. www.flying-pig.co.uk/index.php
