Members who support psychoactive chemical information clearinghouse at levels of $125 or greater are rewarded with one of these lovely hand-worked borosilicate glass CPK-style molecular models, with subjects ranging from the (rather boring) 3-atom linear nitrous oxide molecule to the truly gorgeous LSD-25 molecule shown above, to lower left. This page has some nice shots of the lampwork that goes into making one of these, which is a skill I would dearly love to learn.
