Thanks so much to Dana for sending in this great project from Hacker School! She writes:
Anyhow, we thought you might appreciate this project: we built from a Beaglebone, one of your 5V power supplies and your 16×32 LED panels.
We use LEDscape to handle low-level interfacing.
And we wrote an open source application server to manage queuing and image processing in Python (We would love more contributors!). It can render images, text (with a Project Noto font we have support for Latin characters, Japanese, Chinese, Korean and the Cyrillic character set!), emoji, etc. It connects to our internal chat system, Zulip, but the software is modular enough that people should be able to adapt it for other inputs. The output is Open Pixel Control.

Update from Dana:
As a clarification I just wanted to make sure credit for the low-level
interface, LEDScape, goes to NYC Resistor.
For our project we wrote LEDbot, an application server on top of that to
make tasks like queuing messages and rendering of text/images/emjoi/etc
really easy. https://github.com/marqsm/LED-bot
Featured Adafruit Product!
Adafruit NeoPixel Digital RGB LED Strip – White 60 LED – 1m: You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that’s within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticable strip color – this strip has white-colored flex PCB, which will be less visible against white-painted walls. This is the strip with white flex PCB, its identical to the black 60 LED/meter except it has a different color mask on the flex strip. Read more.
Each Tuesday is BeagleBone Black Day here at Adafruit! What is the BeagleBone? The BeagleBones are a line of affordable single-board Linux computers (SBCs) created by Texas Instruments. New to the Bone? Grab one of our Adafruit BeagleBone Black Starter Packs and check out our extensive resources available on the Adafruit Learning System including a guide to setting up the Adafruit BeagleBone IO Python Library. We have a number of Bone accessories including add-on shields (called “capes”) and USB devices to help you do even more with your SBC. Need a nice display to go along with your Bone? Check out our fine selection of HDMI displays, we’ve tested all of them with the Beagle Bone Black!
