Magic. And the magician didn't bother about changing lists to much.
Use 'supply, like this:
rebol []
stuff: copy []
view layout [
lst: list [across info info] 400x400 supply [
either count > length? stuff [face/text: "" face/image: none] [
lst/set-it face stuff index count
]
]
; with [probe words source set-it] ; get some hints
button "add now" [
append/only stuff reduce [mold 1 + length? stuff mold now/time]
show lst
]
