mokume Gane in progress

Did you know this is how modern computer graphics processors render interesting surfaces nowdays - it takes too much GPU/CPU cycles to compute the curved surface / geometry of the dip then shade it with lighting - instead you use a rough and ready shader program to add some darkness as you approach key points - in this case the the division between bands - basically spoofing the shadow without having to work out the geometry of a curved surface.... anyway sorry for the geekfest but I was particularly impressed with how a real world mechanical artistic process seems to optimise processing in the same way cutting edge 3d and games apps do on PCs and consoles :)

Lunar Eclipse 2011

I was hoping to get the moon going behind Carlsbad power station but
it just got too hazy and light by the time the moon was that low....

There's a couple of photos from 5:50am->. Plus a couple showing my
setup. My exif time data seems a bit screwed up (timezone and DST...)
