i think the exhibition idea has several '+' a) yes - it is fun - and you may engage a younger/bigger public/audience. (they like to play with gamestation and.so.on with vibratiin module) b) you can not (really) use on the net (who has such a mouse? - will be stranger than to use a rare plug-in). c) you can engage sponsors (ie. selling cd-roms + mouse afterwards). + + + d) the net/computer is a pure visual, audielle experience --- missing the tactile sense - therefore ....... e) it is still a simulation of touching (second hand - reality) f) you can reflect the importance of the (here mechanical) interface (for interactivity) - and increase the understanding by tactile experience [correlates with some other mouse idea.s - i forwarded on e-poetry2001 - what does the increase of movement - mouse on the desktop <> mouse on the screen - mean - initiate?] . . .
