I've just built a prototype of a game and the most arduous portion of making the prototype was cutting out the hex-tiles. Just as I finished cutting out the last one, I was struck by the thought that a hex field is topologically equivalent to brick style layout (alternating rows offset) with squares instead of rectangles.
As I'm actively play testing this prototype with real, living people I'm pleased to have actual hexes, but in the future I'll begin any hex-tile based designs with Postit notes in a brick layout for bashing together ideas quickly.
Glad some people find this useful. I'd post some images of the actual prototype I've built, but it seems I cannot add an image to replies. Hm.
