But the biggest changes have all been free. Since I spend most of the day on my computer, I've been collecting Mac icons that fit my theme. My Xterm is now a wooden library drawer with an "X" on it (it's really "for" Mac OSX but who cares?) MS Office is three bubbling beakers in blue (Word), green (Excel), and yellow (PowerPoint). Mail is a retro radar box, Terminal is Futurama's "What If" machine, and Preview is a pinhole camera. TextEdit has a fountain pen. Firefox is a little clank, more scifi than steampunk but only if you look too closely. I have a black steamer trunk for my backup drive and the cushy red chair from the Matrix for my computer. I've changed the desktop background to a Cordovan leather red.
It ain't as cool as this stuff but it's something. :)
