It takes a lot of creativity to turn a blank canvas into an inspired work of art. Japanese artist Tatsuo Horiuchi makes his pictures out of something that’s even more dull than a white page: an empty spreadsheet in Microsoft Excel.

When he retired, the 77-year-old Horiuchi, whose work was recently spotlighted by Great Big Story, decided he wanted to get into art. At the time, he was hesitant to spend money on painting supplies or even computer software, though, so he began experimenting with one of the programs that was already at his disposal.

Horiuchi's unique “painting” method shows that in the right hands, Excel’s graph-building features can be used to bring colorful landscapes to life. The tranquil ponds, dense forests, and blossoming flowers in his art are made by drawing shapes with the software's line tool, then adding shading with the bucket tool.

Since picking up the hobby in the 2000s, Horiuchi has been awarded multiple prizes for his creative work with Excel. Let that be inspiration for Microsoft loyalists who are still broken up about the death of Paint.
