I'm a huge fan of TED videos - I was watching one while doing the dishes looking out over Nottawasaga Bay and thought I'd post it here. From the TED site:

"Before becoming the center of the Western cultural universe, Manhattan was Mannahatta, 'Island of many hills,' in the language of 17th-century Native Americans. Using computer modeling, painstaking research and a lot of legwork, Wildlife Conservation Society ecologist Eric Sanderson has re-envisioned, block by block, the ecology of Manhattan as it was when Henry Hudson first sailed into the forested harbor in 1609."

You've probably seen some great blendings of old and new photos, and I thought I'd give it a try. This one is of a Toronto Archives photo from May, 1923, and the Google Street View from the same corner. I resized the two photographs to match, then blended them using The Gimp.

The streetcar tracks and houses on the north side of McCaul haven't changed too much, but the AGO on the south is rather new. As with many photos of Toronto, the telephone and hydro wires and poles bring the two images together nicely.
