someone I know re: Altoids and Altoids tins:

Way back in the bad old days, high school days, before anybody even knew what Altoids were and you had to buy them in specialty and import food shops I became addicted to them. I went through a tin a week for years. I accumulated so many tins that once I went to GA Tech they became the standard cases for nearly anything electronic I made. There are, or were in 1991, in Brown Dorm many illegal cable and phone junction boxes encased in Altoid tins. A couple of us attempted to build an intercom system encased in Altoid tins but it turned out to be a big pain and was left unfinished. They also worked well as cases for my small explosives experiments.
