I’ve often joked with my computer geek friends that if I was stuck on a desert island and could have only one program, it would be Microsoft Excel. Which is amusing on a number of levels: I have a long history of Microsoft bashing; Excel is not very well known for anything other than number crunching; Real Programmers™ tend to pooh-pooh VBA (the programming language in Excel).
But Excel is incredibly versatile. You can use it as a word processor, the formatting is great, the built in formula language is great, using VBA lets you turn spreadsheets into applications, and more. I even used it to design the kitchen and bathroom tiling for the Electron Workshop.
But a 70+ year old Japanese artist has taken it to an entirely new level: Using Microsoft Excel to create art.
