Over the weekend I added a new menu option called "set scnd", short for "set seconds display". It has three choices: "yes", "no" and "fast".
If you pick "yes", the Ice Tube Clock looks exactly the same.
If you pick "no", seconds are not displayed and a blinking dot is added between hours and minutes. If region is set to US, any leading 0 from hour is removed, and an A or P is added at the end of the clock to denote AM or PM.
If you pick "fast", then every display segment is used like this: HH.MM.SSxx where xx are hundredths of a second, so they scroll by really fast and look pretty nifty. See below video:http://www.youtube.com/watch?v=Ce5uGABRwCk
I'll post the modified firmware in a little while, it's on my laptop which is at home and asleep, wife is going to wake it up for me when she gets back :)
Please pardon the horrible video quality and background setting/lighting :)
