hi. i want to build a component that will be able to show a integer number max 5 digits in the style of the old analog car counters and animate the digit change.

that looks something like this maybe...

i have tried searching for this kinda of examples but i couldn't find anything so far.

in your opinion what is the best approach to achieve this?

i looked at the iphone alarm time picker and as far as i can tell there is only a fixed background and they push the numbers in or out the view. but how do i place the digits in this case and reference them to a particular value?

tnx.
