Below is a program fragment that does what I think you want done. There might
be a slick one line way of doing it or maybe something visually stunning using
object graphics but nothing currently leaps to mind.

Cheers,

n = 4
a = randomu(seed,n,n,n) gt 0.5
surface, dist(n), /nodata, zr=[0,n-1], /save
tvlct,[0,255],[255,0],[0,0],1

for j = 0,1 do begin
wh = where(a eq j)
x = wh mod n
y = wh / n mod n
z = wh / n^2
for i = 0, n_elements(wh)-1 do $
plots,x[i],y[i],z[i],/t3d,psym=2,color=j+1
endfor
