Gold Bubble Spiral

This one is "too busy" to cope with clipart. Which is for the best as I did not have any images to spare.

The wallpaper version is at the preceding link.

Today's Gratitude Item: Crocodile Physics! Rediscovered this lovely little program which is installed on our computers at school (both staff and students can access it). I knew it was good for electricity and setting up circuits but did not realise it could do optics as well. This means that when my students review the light topic, they can use Crocodile Physics to remind themselves of what the various lenses and mirrors do. Said program is reasonably sophisticated and extremely useful.

You would also like to try Stellarium. Its a very addictive portable planetarium, which is GPL licensed (Free as in Freedom).

Thanks for the link. I'll probably investigate it later in the year when we do our Astronomy topic.
