There is a guy in Japan named Tatsuo Horiuchi who makes spreadsheets using Microsoft Excel that display (and print) as original works of fine art. This quote in the write-up at a website called Spoon & Tamago was exceptionally telling:
“Graphics software is expensive but Excel comes pre-installed in most computers,” explained Horiuchi. “And it has more functions and is easier to use than [Microsoft] Paint.”
