[Fluxus] Particle Example in Documentation not working

[gabor papp]

hi,

there are a couple of problems with the example.

first, the double quotes are converted from ", to the slanted version “. 
try to replace them with ", otherwise scheme will interpret these quoted 
expressions like “vel” as a variable instead of the string "vel".

second, the colours are set to 0 opacity here:

>     (pdata-map! ; init the colours
>         (lambda (c)
>             (vector (flxrnd) (flxrnd) 1 0))
>         "c"))
remove the 0 from the end, or replace it with 1.

best,
gabor
