An experiment from Mattt Thompson in how to visualize the input of
masked password fields:
http://mattt.github.com/Chroma-Hash/
Some explanation taken from his blog:
Chroma-Hash displays an ambient color representation of the input as
it is being typed.
Use Case 1: Login Check
If your password normally is represented as “red, purple, orange”,
and after you’ve finished typing you see “pink, green, grey”, you’ll
know you mistyped it somewhere along the way.
