It’s definitely a photoshop job, probably used as a mock up for the work like they do with real buildings or development plans.

I haven’t seen the finished product yet, but I’ll keep you posted if i find it or the video.

Too bad there’s not a larger image available, you can barely see the vegetable nature/origin of the work. If the melon weren’t so obvious with the St Paul’s it would just look like some colorful idealized cartoonish Photoshop creation, in fact the whole image kind of just comes off exactly like a Photoshop created “trick” This would be more impressive if they posted details of the buildings and showed it not in a faked real world setting with the leaves and the water, but in the studio where it was built. Kudos to the amazing work involved, but a D- for the final display choice.

It’s probably more impressive if you’re watching the network on an HD TV.
