This screensaver shows the twitter public timeline, posting a new tweet every three seconds. I wrote it while experimenting with the twitter API and I love watching the deluge of random thoughts.
Once downloaded right-click the file and choose Install (Now packaged in an installer so just run / double-click to install the screensaver). The screensaver requires that .NET 2.0 is installed. You probably have this but it you see an error when you try to run the screensaver you might need to install it. (.NET now automatically installed if needed)
If you don't see any updates (just a blue screen) make sure that your firewall is configured to allow TwitterPublicTimeline.scr to access the Internet.
If you have any problems get in touch here. Please leave a comment on this post for any feature requests. Also, if you like the screensaver please follow @CatfoodSoftware.
(Updated 2009-02-25 to 1.00.0080: Improved tweet display and support systems with multiple monitors.)
(2009-04-22: Profile pictures aren't displaying correctly at the moment - you just get the default twitter image. This is a known issue with the Twitter API. As soon as the Twitter bug is fixed the screensaver should start displaying the right pictures again.)
(Updated 2009-05-08 to 1.10.0138: You can now add your own account (or accounts) to follow as well as the public timeline. Colors are also now configurable. I've added an installer so just download and run to get started.)
