Coffee Space 
I recently read a blog by Terence Eden and I was suddenly reminded that I always wanted to create a montage of the preview images from the articles.
Unlike Terence’s images, mine are already 256x256 in size (by design).
The montage was pretty easy to generate:
0001 montage **/**/**/preview.* -tile 16x16 -geometry +0+0 montage.png
Without further delay, this is the result:
That is 16x10, or 160, different preview images (not including the one in this article)! Quite cool!
