Might be better IRL, though.
it's indeed better IRL, it was surprisingly hard to film a flickering display with a flickering scrolling text :-)
Nevertheless, it's quite useless of course
Just a little toy to learn a bit more about interfaces and matrix-translations and stuff.
There's someting wandering around my mind of building a 60 cm width by 240 cm high led panel dispay.
We'll see how far i'll get and what resolution can be reached before my mind or budget runs out.
As a small exercise in my progress towards to ultimate tweetshirt, I created an interface for a 8x8 LED matrix display.
It doesn't do much at this moment: a program runs on the PC, fetches your latest tweet and controls the USB attached LEDs to show it as scrolling text.

The hardware is from Byvac and is cheap and easy, but also a bit limited.
The software is by me and uses their IASI-2 protocol
The scrolling is in fact much smoother then appears in the video.
Maybe I'll rework the hardware interface to control a 4x4x4 LED cube.
I ordered an Arduino today, which will allow much more low level processing and control for these kind of things
a 8x8 RGB display seems a nice project to start with, hoping to scale up to a 16x16 grid if things are going well.
