This clock may be a challenge for a geek or to anyone interested in working his brain. Just need to learn the ten symbol codification because instead of each number there is a special symbol.
Don't worry, there is a routine implemented that allows the user to self-define the alphabet when he likes. Worst case, if you get bored of symbols, anytime you can insert numerical standard IN12 tubes and you'll have a "standard" clock.
