[Taler] Taler user interface idea #2

[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

Here's an idea: show on the screen an animation of paying each of
banknotes or coins that add up to that amount.  So if you pay 43
euros, it shows you a 20 moving across the screen, then another,
then 3 one-euro coins.

These animations should not be photorealistic.  That would be
difficult, maybe illegal, and certainly pointless.  They should
give the user the feeling of "I'm spending money here."  They should
take a few seconds, so it sinks in.  The more money, the slower.

Once again, the point here is _attention_, not _information_.
It is "remind me of what I know -- don't let me ignore it."

Like the other feature, this feature should be enabled by default.
When the user asks to turn it off, the program should say, "Most people
spend more money when payment is easy.  You might be an exception,
or you might be so rich it makes no difference.  Are you sure you
want to turn this off?"
