Tuper Tuper are Atsuko Nakagawa and Tatsuya Kameyama. There are two Japanese artists, and if I understand it, are right in Tokyo. Tuper Tuper is the name of their studio and on the site are all the work they have done illustration and graphic design. But in my opinion their strong point, very strong indeed, are the laboratories. So suggest you look at this section because it is fantastic. I dream of the day when we do a lab in space so large and with all this good things of material recovery. I try to gather around ... but we can get our labs with only one suitcase!
