I have developed an interest in Euclidean geometry. I must confess I know very little about it, however I find it thrilling and I desire to learn more.
In the process of studying Euclid's Elements, I came across this handy, dandy little toy called a geometry applet. Click here if you want to examine it. [Warning: it's addictive, but I have not figured out why!] It is a rather cool little device.
