Mapping
Almost entirely unrelated to the topic of the article, I know, but I remember once - back in the mists of the early Internet - having a little Windows program that used to map out my wanderings round the web and present me with a sort of atlas of the bit of the Internet I used.
It was all stored in a local file, and it probably served no practical function except to give me pretty diagrams to look at... Wish I could remember what it was called. Anybody know if there's any similar toys out there today? If I type in 'Internet mapping' I just end up with (horrors) serious, network-management stuff I don't understand. :o)
