[fluxus] howto call more objects into the scene

[alejo.duque at europeangraduateschool.net]

hiall, im needing some help on understanding how can one create in the
scene new objects..ive been looking to the grab ungrab functions but i
will like to say have new cubes added via an OSC message that counts up
randomly.

so if it changes from 1 to 2, there will be a second cube in the scene...

i have this very basic code, and im sure is not the right way...im
beginning to learn about scheme so plis forgive my newbiness

; this is a very basic example, few things are not ready there, as said
above i want to find a way to solve the creation of new objects in the
scene according to an incremental number that arrives via OSC.

thanks for any pointer,
/alejo
