During the last days I've been quite busy (moved to a new apartment) but managed to write a new win32 application nevertheless (took me two evenings, overall eight hours of work).
The original idea was that I wanted to write some application which actually made use of the LED notifier device - besides of just "manually" lighting it up in different ways. Seeing that Scotts "Gmail Alert" (which I'm using) seems to evolve into a very nice full-featured email client at present time, I didn't feel any need for writing something email related - so I decided it would be a good idea to do something with twitter (after all, their API is nice to work with, IMO) maybe. After searching for a suitable twitter API wrapper for vb.net, I settled on using the "yedda_twitter" library for the purpose (see http://devblog.yedda.com/index.php/2007/05/16/twitter-c-library/ for more details). The timeline is being fetched, saved and parsed as XML file. The user interface was designed based on bitmap graphics created while playing with the new gimp 2 (making it possible to add skin support in the future if needed), Here's a screenshot of the main window:

I included a checkbox to enable the thing to autostart when windows starts up, the application remembers your twitter account data (but it hides your password, of course!), and checks your twitter "friends timeline" every minute, then it decides whether the last tweet is a new one or not, and in case it IS a new tweet the LED notifier is lighting up in turquoise, tray icon changes color to red, a balloon popup shows up displaying the new tweet sender's name and actual message, and on clicking it, the twitter tray icon becomes normal colored and the LED goes off again.
"Twittercheck 1.05" is available for download here:
http://sourceforge.net/projects/twittercheck/
Application requirements are installed "VisualBasic PowerPacks 3.0" and ".NET Framework 3.5 SP1", and of course you need a twitter account too, if you want to make use of twittercheck's features.. :)
