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?]
