I came across this blog recently (thanks to Andy Hoare) – really impressive stuff.

The faded glory and gothic weirdness of 40K. (This is an image from Tears of Isstvan – check ’em out).
It’s an awesome 40k gaming/painting/modelling blog. These guys really get the look and feel of 40k – no real surprise, really, since John Blanche is part of their gaming group…
Inspiring stuff!
