Here is a great tip we got from Mark Thorpe and it has to do both with TP rolls and with Macro photography. It turns out that there is a great way to diffuse the the $750 Canon MT-24EX Macro Twin Lite Flash.
At heart the MT-24EX is a dual strobe system that sits around the lens and enables getting the light pretty close to your subject from two sides. Close means soft light (I mean think how huge a strobe at 3cm must look to an ant), and two-sided-illumination means significant shadow reduction.
But PixelHobo who need just a little bit more diffusion, attached two rings made from old desk lamps covered with toilet paper to get an even bigger light source. Not really sure if this is more simple or more clever.

Yup, toilet paper is definitely a must for photographers.
