(2) Online Etymology Dictionary. D. Harper. Nov 2001. 1. A substance formed of clay, kneaded, moulded, hardened by baking with fire, or in warm countries ancient times by drying in the sun; used instead of stone as a building material. 4 transf. a. A brick-shaped block of any substance, e.g. of tea; of wood, for a child to play with. box of bricks: a box of wooden blocks for a child to build with. [Etym.] ca.1440, in sense 4a, 1861. From OFr. briche, 1264 brique, 1457. Probably from a source akin to MDu. bricke, in the sense of ‘piece, bit, debris’.

Fe·tish n.(1,2)
1. a. Originally, any of the objects used by the natives of the Guinea coast the neighbouring regions as amulets or means of enchantment, or regarded by them with superstitious dread. c. fig. Something irrationally reverenced. [Alt.] An object of irrational reverence or obsessive devotion. Also: fixation. [Etym.] 1613, in sense 1c 1837. From F. fétiche Pg. fetiço ‘charm, sorcery’. From from L. facticius ‘made by art’, from facere ‘to make’.

So then, the site is an obsessive, irrational devotion to a brick-shaped child‘s building block. I think that pretty well covers it.

The third edition of Brick Fetish has been completely rewritten, considerably expanded, and newly annotated. It includes, among other things, additional coverage of early wooden toys and of Hilary Fisher Page/Kiddicraft, as well as a reevaluation of the early Lego licenses.
