The story so far: driven mad by eight weeks of working from home, hardly daring to go out, and having hardly anywhere to go our intrepid explorers hold a large spring-cleaning exercise that takes most of a weekend.

Among the things that hove into view we find a Bonk t-shirt, and by some diligent detective work on this very site, I can say precisely when and why I bought it. Domestic archeology in action!

Boing Boing started out as a zine in 1988. Recently I discovered a slightly mutilated Boing Boing t-shirt that I had brought with me to Finland over twenty years ago.

I decided to photograph it, and post it here, before using it as dust cloths.

The idea of representing ideas or thoughts diagrammatically is not a recent one. As early as the third century, Porphyry of Tyros produced map-like images to demonstrate the structure and workings of Aristotle’s philosophical concepts.

However the current usages of the terms “mind mapping” and “concept mapping” are relatively recent. Both terms have known inventors, who have spent many years developing their ideas, and both terms arise from theoretical assumptions or research. Despite the apparent similarity of the terms, and despite the fact that both describe methods of representing ideas diagrammatically, they have completely different aims, and work in very different ways.
