But the Cube still seems really dated to me
The cube is slightly less dated then top hats and rabbits, girls in sparkly bikinis and those terrible haircuts magicians seem to go for. (Mullets?)
And theatrically, using your magical powers to solve a puzzle seems low on the scale. Why not magically fill in the answers to a crossword puzzle while you're at it?
Finding a specator's card or Producing a handful of change is pretty low on the scale too.
But then again, it is not what you acheive but your audiences response to it. Anyone who has spent more then five minutes trying to solve one of those blasted things would be gobsmacked to see someone do it in a second.
I know, I use the trick all the time.
but no magicians seem to have jumped into the bell-bottomed disco era.
I admit that I haven't caught your act recently, though.
I have a 70's magician character (on articulated stilts no less)
