Wow . . .you need to check this out. Maine's own, Sharon Betts, just blogged about Time Space: World on Sharon's Share blog. This is yet another powerful, yet simple to use, online tool to make connections with photos and events. Along with one of my favorite tools, Cooliris (formerly PicLens), it is easy to scan the planet for that needed image. Just think of the possibilities!
There is an embedded version of Cooliris below, but to gain the full power of its capabilities, a browser plugin needs to be downloaded here.
