Here's a tip for Google: when you have a new product to announce just present the actual thing.
When you create promotional videos like the one designed for the new partnership with Lego called the Build with Chrome app, you end up setting up a false expectation. The video, embedded below, suggests the new service will let you build photo-realistic shapes and drop them into high-def Google Earth-style landscapes. That is not the case.
The visuals in this video bears almost no relation to the actual product.
