... you will find a lot of persons.

No, i am not schizophrenic (i believe), but last weekend i played around a little with the new Silverlight 2 Deepzoom Control [0].

... and that's the result: my cat, my city, my self (only visible in IE with latest Silverlight plugin)

use mouse for zooming and moving

What you need are some big very detailed images and the deep zoom composer [5], which generates the tiles. Then reference the generated output to the MultiScaleImage Control:

The hardest but also funniest thing was to get a nice detailed picture. I only found the virtual pixel town [1] from a german pixel project. Unfortunately most of the good panorama gigapixel images cost a lot, so i decided to generate my own ones;) The first is a sweet "fear-me" cat [2]. I converted it to ascii text with the help of the mosascii m2 tool [3]. And the big mosaic of myself i created with andrea mosaic [4].
