Compact fluorescent bulbs might be magnitudes more energy-efficient than their incandescent counterparts, but they're also all kinds of industrial and ugly looking. And if you don't have a lamp or fixture that hides them under a shade, consider Guus Oosterbaans' approach to making them considerably less of an eyesore.
Like moths to a light source, Guus' DIY approach involves cutting out a series of butterfly shapes from transparent tinted acetate, and then attaching simple brackets so the faux insects can be clipped onto the CFL's spiral bulb. And it doesn't have to be bugs. If you're going to the trouble of cutting these out you can make them any shape you want. Tiffany, anyone? [Findings of Guus Oosterbaan via Notcot]
