Well, the openGL code is no problem. I've yet all the source
to load texture, draw it, and so on working. I was thinking in
a component with the odometer behaviour, to know how the
'acumulative' scroll could be done. For every digit position
you can draw a textured number and translate it for an amount
at every constant time. How to calculate this messurements are
my question.
