Ever use the opacity property to give some eleme3nt a see-through effect? It's pretty cool the results you can get, but you can also run into some problems. For instance, you have some container of elements and you want to give that containers background a see-through effect. So apply an opacity of 0.50 to the container and your done! Well, not so fast.
Some of our hardware that we are currently using at work required time to fully charge up before it could be used again. After 'x' amount of seconds the signal would be fully charged and ready for action. Now the typical way that this could be presented to the user would be an on / off state where off is when the signal is not present or when it is charging and on when the signal is ready to be used. But, what about a progress bar! Just slap in a progress bar and bind its value to the signal and wa-laa, done.
