I love seeing the imaginative things that people create using either Freetronics products or ideas from Practical Arduino. Phillip Stevens has been working on a retrograde clock, and it's a great example of using the prototyping area on the TwentyTen to save fitting a prototyping shield for just a few parts.
Check out Phillip's excellent work on his blog:
