Microsoft has finally closed its acquisition of Seattle-based Seadragon Software (see this story today). These things apparently take some time to work through; we got wind back in late January that this was wrapping up.

The financial terms of the deal weren't announced. The acquisition isn't large enough that it would have a material impact on Microsoft, and as such the company doesn't have to announce it.

Seadragon has some pretty impressive demos of its technology. You can see them here.
