I've got to do a talk in a couple of weeks and I think it's going to be about screens. A varient on this piece from The Observer but perhaps a bit more optimistic.
So now, of course, I can't help seeing screens wherever I go. This is possibly the cheapest I've seen to date. A Sponge Bob "Multi Image Projector Pop" (that's what it says on the side).
It's like a small, cheap, externalised ViewMaster, without the 3D. Or something. It's a sweet dispenser with a screen built in as the disposable gimmick.
That's the future for screens - disposability. Ubiquity through gimmickry.
