Mats continues his challenge of designing one PCB every week.  In week 15 he came up with 14 segment display- Twittorama:

Displaying tweets isn’t anything new, but most I’ve seen have a small display and scrolls the tweets. I want the full 140 characters to be visible simultaneously. So I put 10 of the displays (20 characters) on a pcb with a heap of shift registers, resistor arrays and some n-fets.

Then I just daisychain 7 of the modules to get up to the 140 characters. Adding one more unit, placed on top of the 7, will give space to display the name of the sender as well.
