Video: Will Chromecast revolutionize online shopping?

This is fun: Independent TV apps developer Leon Nicholls has developed a demo app that shows how online retailers could leverage Google’s (s GOOG) new Chromecast video beaming stick by allowing customers to easily display products on their TV set.
Nicholls built a simple mock-up app for, which is sort of like an Etsy for 3D printing enthusiasts. Check out a video of his demo below:
This is obviously just a first demo, but it shows some interesting potential for Chromecast, or any advanced screen casting solution for that matter. Instead of confining the shopping experience to just a tablet or phone screen, retailers could give customers the option to look at bigger photos or even videos of a product on the TV screen.
One could even imagine that retailers could use the TV as a kind of in-house hub to enable a social shopping experience, with multiple users finding different products on their mobile devices, and comparing them together on the big screen.
