I haven't seen this one in a while.
It simulates a alphabet tumblar, like the one on 'The Davinci Code'
I put it together in hope of using it as an input string and dragged it out,

L/R d-pad to move the highlighted letter.
U/D d-pad to change the highlighted letter
The amount of letters can be changed with the square (less) and circle (more).
