Strong points
It's quick and flashy to gain attention
It's relatively easy for a beginner
And can be used with any cube puzzle 3×3
Weak point
As a hobby cuber I am familiar with a wide range of algorithms and solves which could make this almost seem to obvious. Be prepared for those individuals that naturally see patterns and finer detail to potential notice the plot quickly.

In conclusion, great as a carry around if you already have a cube anyway and if you show it to cubers be an expert at it and show them right off before they get a chance to visual cue in. Perhaps utilize some alternative misdirection.
