Fantastic, clear basing is really taking off, I think.
Here at Sally 4th, clear bases have been our no 1 seller for the last 6 months, we ship out thousands every week of every size and shape you could imagine. We even have some special ones for random movement of figures that have 1-6 engraved around the edge!
I'm re-basing all of my WW2 figures so that they match the terrain, because it's not just the multi-season thing with figures on grass or snow, on one gaming board you could have beach, road and grass.

Here's some of my German Para's blending in with the floor boards. Lots more photos in our basing gallery.
