It shows a better version of the image zooming (Seadragon) and a really cool shadow effect, which kind of looks like xrays a one point

Skip (11.30) or stay to the end to see the shadow box.
I love the coke can effect.

Cool! My paint app works exactly in the same way as how they do it with shadow box.

The paint app is really nice.The camera feed is processed and presses are converted to textures that are aplied to the table with different opacity’s based on the time the object has been recognized for.
The coke effect is just superb , somebody should try to replicate the app.
