Projections in 3d plot


I have a 3d plot and, in the 'walls' of the plot, I need
to plot some 2d functions to represent the projections of
the 3d function. Is there any way to do or emulate that?
The functions are actually very simple, so a work around
might do the job.

Also, is there a way to change the plot color? I tried
using the 'color' keyword, but that didn't work. And I
can't work well with the ticks. These two aren't really
that important for what I need the plot, but any idea
could help.
