Like I don't want to offend you or spoil the fun.
But is this real?^^
Looking closer I can see that the stickers always sort of reflect the other cube but the stickers also always just exactly end up at the other cube. It looks weird.
Are you kidding me?If this is a hoax it's cool. Not as cool as Tony's 9x9 but also good.
I made a hoax once. I drew a 9x9x9 cube with rhinoceros 3.0 and than with photoshop put it on my desk.^^
Fusing 3x3 and 5x5 is funny though.
If this is not just a hoax, I shall be slapped.
Tell us!
(I really really hope that I am not going out on a limp with this! That would be

)
edit: Yeah, I think you made the reflections by using transparency didn't you. I can see the 5x5x5 "through" the 3x3, rather than a reflection in the stickers of the 3x3. Nice trick to create the illusion though. Wow, again if this is real I will have to put my head on the keyboard and close this laptop.
