#619: Spreadshirt

Many people don’t want to get personal with arithmetic, but I suspect that, for a sizeable minority, there are certain calculations which have a particular significance: the performance of one’s favourite stock, the growth curves of one’s children, the sales of a book you wrote, the original Google businessplan or your marks in some exams at college (however bad they seemed at the time).

Today’s invention is a shirt which can be printed with a checked pattern, just like a spreadsheet, but whose cells contain a calculation or dataset that means something particular to the wearer.

It would be possible to arrange for this printing to be ordered online, by uploading your own speadsheet. This would offer a way to show off one’s data design abilities via a unique item of clothing -and provide math geeks with a conversation starter.
