Satheesh wrote about his [friend’s binary watch]. I too saw another crappy watch in Hyderabad Cenrtal - it has minutes on the x-axis & hours on the y-axis. There are perpendicular lines that intersect these axes. Their intercepts denote the time of the day. There is a side-button which on press, gives a digital-time in numeric form.
I have one more idea of representing time - rather simple - have an array of 5x12 LEDs (SMD types), capable of displaying RGB. where: - R - denotes hour of the day - G - denotes minute of the day - B - denotes second of the day
At 1:15 am, LED glows in RED (hour) & LED glows in GREEN (minute)
At 10:08 am, LED glows in RED (hour) & LED glows in GREEN (minute)
At 05:00 pm, LED glows in RED (hour) & LED glows in GREEN (minute)
At 12:00 pm, LED glows in RED (hour) & LED glows in GREEN (minute)
At 12:00 am, LED glows in both RED (hour) & GREEN (minute) - giving a REDdish GREEn lOOk.
There shall also be a blinking & moving BLUE light - jumping to the successive LEDs - denoting the second of the day. Racing Blue - wouldn’t be cool?
