Anyone used Rubiked for walkaround?

I'm wondering how quickly the image resets.

ACtually, I'm thinking of doing a longer routine where the spectator can check his email twice and see a different cube each time (without realizing he's seeing a different cube, since that'd obviously blow the whole effect)

To clarify - I'd perform Rubiked, then solve the cube and immediately set if for Brundage's solution.

The "sucker" gag is the cube doesn't look solved, yet I act like I just accomplished something great. THEN they check the email and see that the image matches the current cube.

The implication is that I didn't just solve the cube ... I actually duplicated the spectators' own scramble.

The final kicker is obvious - I instantly solve the cube for real
