I might be a little late on the uptake here, but last week I saw, for the first time, these giant ad-screens on the London Underground.

I’m in two minds about them. Part of me is amazed at the paper-thin giant screens and the sheer level of 50′s style vision-of-the-future they exude. Another part of me is reluctant to accept yet another level of intrusive distracto-vision into my daily life. Still, I guess I’ll only start worrying when I’m faced with Minority Report-style hologram advertising

Now – where are the jet packs and flying cars?
