The scale of the universe 2

This is an updated and improved version of an app I posted a link to last September. It is awesome, and I mean that literally.  Click on the picture. 

Visualising the scale of the Universe

Try this out, a tool developed by Cary Huang to help vosualise the scale of the universe, using an app rather like Prezi - maybe it is Prezi.

I'm trying to think of ways this could be used this in teaching - years ago Alison Tomlin and I modelled the solar system with students standing on a scale of 1m miles to 1 inch: Mercury was a few inches from the sun, someone was a mile away (I guess Neptune) and someone else (Pluto - this was before it was downgraded) was 60 miles away!

This app is awesome in the same way.... http://primaxstudio.com/stuff/scale_of_universe/
