Kaiyodo has just release a series of gashapon magnet toys of micro-organisms from Tales of Agriculture (Moyashimon) a manga/anime about a college student at an agricultural university who got the ability to communicate with bacteria and other micro-organisms.
I think these toys (and the manga Moyashimon) would be featured in the Whole Earth Review magazine if it would be still published or maybe I'm just an etnobotanic otaku, tripping on plastic toys, who spent countless childhood days programming botanic simulation softwares on his Commodore 64...
