A Twitter Wall is a projection of short messages from a micro-blogging application, which is used for events – a “wall” with all the live tweets containing a given hashtag.
The next version of the Flickernoise video synthesis software for Milkymist will allow you to set up such a “wall” on top of your VJ performance with only a few clicks.
The first step is to connect your Milkymist One video synthesizer to the internet. With most network setups, this is as simple as connecting the Ethernet cable – the device will then automatically use DHCP to configure itself. If it does not work on your particular network, click Settings on the bottom of the Flickernoise control panel, and enter the network parameters manually.

Then, click RSS wall in the control panel, and click Enable and OK. By default, it will search for posts containing the hashtag #milkymist on the micro-blogging service identi.ca. To change the hashtag, simply replace the part after ?q= in the URL. If you want to use Twitter instead, simply use an URL like http://search.twitter.com/search.atom?q=milkymist.
Twitter wall configuration
You are now done and tweets containing the hashtag will be displayed live on top of the visual performance:

To advertise the twitter wall to your guests, you can use the Idle message option, which will display regularly a fixed text in the absence of tweets.
If you are running on a LAN without internet connection, you can also use OpenSoundControl (OSC) to send the text messages. Just send a string to the OSC path /osd. The Flickernoise OSC server is listening on the UDP port 4444. So, with oscsend, you could use something like this:
oscsend 192.168.0.42 4444 /osd s Hello\ World
