The desktop is made from a string of custom Rainmeter configurations on a Halo 3 background image. Rykennedyan’s list of features:

• Grenades – Each grenade launches a specific application. I currently have them set to, from left to right, Pidgin, Steam, Foobar, and Firefox.
• Power Drainer – Opens a Shutdown menu. You can choose Shutdown, Restart, and Sleep
• Health Bar – Displays current track progress, with artist and title above it.
• Battle Rifle and Ammo Count – Displays current unread message count from Gmail and the Battlerifle opens Gmail.
• Ammo Clip – Top clip is download traffic; bottom clip is upload traffic.
• Radar – As of now, all this does is download and save an image for the local radar from Weather Underground. I’m currently editing a GIMP script which will automatically crop and edit the picture to display properly upon download. What you see here is the intended look. It also displays the current temperature.
• Time and Game Type – Display current time and date.
• Blue Score and Red Score – Display current CPU and RAM usage.
• Player Callsigns – These behave just like my TweetScanner skin.
• Battlerifle Ammo Count – Displays current battery status; it displays 0 in this picture because I’m using my desktop which is not on a battery.
• Also, the visor outline is done in Rainmeter as well.
