Electricity pylons, or transmission towers, usually aren't the most interesting structures, just basic towers that keep electrical wires aloft. But some architects have designed innovative towers that are more than mere eyesores.

These are cool, but I feel the need to defend the standard pylon. I love 'em, they're pure function and that appeals to me. I actually think they look awesome stretching across the landscape. (Note: I do not have them in my backyard, that may be a very different proposition.)
