These are very clever and cute executions for IBM via Ogilvy. As seems to be the trend these days, create something that you can shoot for a viral video, and then you don't really have to fully execute it.
I point that out because if you really think about it, these have some serious liability to them. Sharp corners, things that one can slip on, vandalism, etc.
But for a video they work very well and show the brand off in a creative way. I would have liked them to show a few locations for each to at least TRY and convince us that these truly existed outside of a shoot, but we can only ask so much.
