Seems like the original LJ Images has been overloaded (the link spread like wildfire), so here are two replacements: perurb and n0wak (mine. Please don’t kill my server too.)
One of the problems with posting the original link at a place I can not mention (first rule) is that my account there is old and I’m using a stupid username. So when that username gets referenced in thanks on other sites (which, obviously, also can’t mention the source — first rule and all), I cringe. “singularity.” ugh.
