Post your cool pictures here

[krazer]

On some of the other (non-laser) forums I frequent, there is an ongoing 'post your cool pictures here' threads.

Some ground rules-
1. Picture must have been taken by you, or be of something you were involved in
2. No double posting
3. You must have at least 1 picture per post, preferably limited to 1 theme per post
4. Rules 1-3 may be amended for sufficiently awesome pictures

My initial contribution:
An Avia Thor 15w 355nm laser which was destroyed in shipping, and turned into a Frankenstein laser putting out ~50w
