On my desk at this very moment:
ancient HP Laserjet IIP
computer
monitor
2 little speakers
wireless headphones
telephone
last night's Scotch glass (yes, I'm at home, not work)
this morning's coffee cup
scanner
aromatic candle (lit)
keyboard and mouse
empty ashtray (haven't lit my first yet)
radio
clock
desk lamp (actually, it's on top of the computer)
assorted pads of paper
various tins full of pens, pencils, rulers, scissors, and other assorted junk
wire rack full correspondence I'll probably never answer
pile of software CDs
only one book, instead of the usual dozen, Roger Penrose's The Road to Reality.
large desk pad displaying a map of the world in the Mercator projection that makes Canada look four times as big as the United States.
So, I hear you thinking, how big is my desktop? Lemme just whip out the tape measure here... three by six feet. I cut it down from an old slab door.
