These two posts on Mike’s blog caught my eye:

1. Jelly Sensor for earthquakes - a fun application but requires Yahoo Widgets.
2. Subtangent numeracy maths resources - Countdown - after visiting the link contained in the post what I really liked was the educational version with additional controls.  You can also download the program as a flash file for use offline.  While at the subtangent website I found stack loads of useful maths resources and programs, I think it will take some time to go through them all.
