I’m intrigued by Simile. It allows anyone with a little HTML experience to create their own google map mashup. The mashup samples on the Simile website are fairly sophisticated and they show the potential types of data that can be used.

I’ve yet to create my own mapshup but after reviewing their tutorial it does not seem too difficult. Now I just need to come up with something to represent and I’ll be on my way to mashup mania.
