I mentioned this in another thread (about Clearscript), but I thought I'd post the possible 7-segment LED forms in different ways, in case someone would like to use it as a basis for their own alphabet.

I will put descriptive phrases in the picture titles, but the pictures themselves should be worth a thousand words (grin). The first picture is kind of a confusing jumble in places, mainly because a lot of the forms are not continuous, and segments can attach to different symbols. This inspired me to drop more than half of them. Hope someone finds them fun to work with!

Very interesting. A digital clock could actually show messages without extra LEDs. Good idea. Now, just give a value to the symbols and you might be on to something...
