[fluxus] (draw-cube) (hint-wire) weirdness, plus a few miscellaneous issues

[Claude Heiland-Allen]

Hi all,

A few quick things I noticed with fluxus-0.10rc2 (Linux with proprietary 
ATI drivers, which might make a difference?)

(draw-cube) doesn't allow its (wire-colour) to be set, see attached 
script.  (build-cube) doesn't have this problem...

(draw-cube) has an extra line around it with (hint-wire) turned on, and 
zooming inside the cube makes it looks like there are in fact two 
squashed cubes stuck together instead of just one.  (build-cube) doesn't 
have this problem...

I was playing with some 3D ripple effects, with a moving point leaving a 
trail of spheres that expand and become less opaque.  Then I decided 
that randomly placed cubes expanding in that way looked nicer.  See 
attached script, some screenshots are here:

(the Cube Rain images are the ones relevant to this email, in the likely 
event of me adding more images to that page)

One weird issue, sometimes (albeit rarely) when I hit F5, all the 
objects appear black, see the third Cube Rain screenshot for an example.

And, more of a Scheme question than a Fluxus question, is there a faster 
way to remove something from the wrong end of a list than:

(reverse (cdr (reverse L)))

And finally, if I hit Ctrl-F then Ctrl-W, my window manager decorations 
don't come back (I'm using Fluxbox).  Is there a way to make them 
reappear so that I can quit without having to Ctrl-C in the terminal I 
started Fluxus from?

Thanks,


Claude
