If you’ve had a look at the amazing Hard Rock Memorabilia site that Vertigo built for the MIX08 Keynote (and then put live for good measure) you’ve probably been impressed at how easy it is to zoom in and out of the dynamically re-arranging collection thanks to the Deep Zoom feature in Silverlight.

Although it’s pretty astounding to think that Deep Zoom facilitates the delivery of megapixel and even gigapixel images that can be panned and zoomed into with amazing speed (and low bandwidth consumption) the story doesn’t end there.

Thanks to a concept called sparse images it’s possible to embed images and collections within another image so you can continue zooming down past the point where pixels blur into entire new worlds or collections – it makes the imagery almost fractal in depth and navigation possibilities.

So where can you see it in action? Simple … go to the Hard Rock Memorabilia site and have a look around. To give you a clue I’ve included a picture of what you’re looking for with this post, but if that isn’t enough then have a look here (but don’t you want to try finding the Easter Egg first…).
