3V1171.02 Letter roller: compared to Rubic’s cube (4/7/81)

Peggy has played with Rubic’s cube for several weeks, first destroying the complete pattern by a single or double twist, then “fixing” the cube by reversing the operation — uniformly with great pride and delight. We, of course, applauded her efforts. This was not at all surprising in P167 that Peggy took the letter roller and rotated the letters, then returned to the original word.

She continued to play with the device for a couple days after P167, then it dropped from currency. I intend to purchase one with capitals instead of the lower case letters.
