I might consider it.
It's actually not that hard, it's mostly a hardware thing with this; you need some stuff to keep the camera absolutely still with these longer exposures.
Steel leg tripod and remote shutter release did wonders here (the other photos in this thread are handheld short exposures).
Tried reverse lens photography.
Taken with an 18-55 mm lens mounted backwards, set at about 20-22 mm f/18. Exposures at around 1/50 s at ISO 1600. I definetly "need" a ring flash; these are about 20 cm below 2x1200 lm compacts.
Dirty optics become painfully obvious this way, and even at f/18, depth of field is barely 2 millimeters.
