I'm extremely impressed with the implementation. I'm not sure what I would say if presented with a design like this slider for web. Wouldn't have imagined it would work this beautifully as well.
It definitely moved the opposite way I expected it to, but this way grew on me, hah.
It's not a perfect UI element - you can't actually see the options without scrolling through it all, but I could imagine something similar being a pretty cool little thing in the right context
Amazing showcase.
