This is absolutely brilliant!

If you do anything today then make sure you go to this website and download Triptico which is a free (at the moment so hurry) interactive whiteboard tool that you download to your desktop and so can work on any whiteboard.
Inside Triptico there are 23 different applications all based on real life quiz shows, fancy graphics and sounds. The best bit is that every single application can be completely customized for your subject. Seriously this is brilliant, please give it a try – below are 3 examples that I quickly tried but there are still another 20 more to try.
I am indebted once again to the fabulous @Kristianstill who shared this with me in the first place 
In the famous words of Gary Barlow ‘it only takes a minute…’
Happy Triptico-ing!
