Indexcard and LEGO
When I was child, I do loved to play LEGO brick. It is piece by piece, as you know, with various color and shape. It is possible to build almost anything.
Writing an indexcard is somewhat like making a piece of brick. After accumulation of indexcard, the set can be organized/reorganized to build something larger structure, e.g. report, paper, book etc..
To realize such re-usability, a contents of single indexcard must be concise. I think the size of 5×3 indexcard is the best for this purpose.

I played with LEGO aswell. And as you said, Hawk, I just flip my cards around to do my thinking. Visualisation of my brain-movement by driving around the cards on a table or a board.

Yep. Indexcarding is nothing but fun for who used to play with LEGO :)
