I've had zero success in finding a MASSIVE digital clock. I'm after something with digits about 8 inches tall, preferably LED not LCD. Perhaps there is a clock circuit I can buy or build and huge digits I can buy? Or maybe make the digits myself out of loads of LEDs? Any ideas?



Some ideas for you.
I found it several years ago, was surprised to see it still around when I Googled a few minutes ago.
