ugly, bulky, and likely ineffective. The iBand from Tech21 isn't particularly attractive nor svelte, but after watching the video below there's little doubt about its effectiveness. It's made of a substance called d3o, which is a fancy orange non-Newtonian substance, starting out stretchy and gushy but, when put under pressure, hardening and protecting its precious contents. We've seen this stuff applied to high-impact applications like motorcycle armor, but we're glad to see gadgetry getting a little attention too. The video is a bit curious as it appears that the d3o is just applied around the edges of the case and yet the enclosed device survives a face-down landing, but it's an impressive demonstration nevertheless. Right now the £15 ($25) iBand is only available for the iPhone and iPod Touch, but future gadgets should receive the oobleck treatment soon.
