Well it's been a long time.  Not because I haven't been working on the 100 but because I've been away for the summer and had a computer failure meaning that I couldn't download any pictures or make fresh posts.  In case you're interested the school did well this year and the Maths department held it's own so my wife and I had a few pitchers of beer in sunny Florida on the 22nd to celebrate.  I couldn't face Windows 8 so decided to go for a Macbook; the main issue with this strategy is that my laptop broke a month or more ago and I decided to wait for the new version to be released.  Only the second day of ownership so I haven't figured out how to post pictures yet, I know, I know, I'm slow.
