looking for ideas

Hi all, I'm looking for new ideas for advanced in car electrical mods. I would like to add some more tricks to my in car electrical, but I'm running out of ideas. I'm open to any ideas, especially unique things that most people wouldn't bother with. Here is what I have so far: Vehicle = 2005 Scion xB automatic Alarm = Viper 791xv Installed features: Remote start 2 530T window modules. All 4 windows roll up when armed and can be rolled up or down with the remote. Battery backup 1 regular siren + 2 pain generators Hidden toggle switch to disable sirens when they are unwanted Shock sensor Valet switch Hidden Fuel shutoff switch Other misc electrical: 1.2Ghz PC mounted in dash with 7" touch screen. This serves as my head unit / multimedia player. GPS XM radio Wifi Slot load DVD drive In Dash USB port Wireless mouse Rear view camera that auto switches when in reverse. The fuel door cable has been replaced by a push button and a solenoid. This is also tied into an output on the alarm so it can be opened with the remote or the button where the factory lever was. 8 LEDs have been mounted in each "oh crap" handle. These are connected to the dome light and come on whenever it is on. They also fade out with it. 8 cold cathodes are installed throughout the car. 2 are mounted inside the engine bay and come on when the hood is opened via pin switch. The other 6 are under the dash and seats and come on with the door trigger. All of the lighting is white and none of the bulbs can be seen directly. There is just a white glow throughout the car. I have also converted all of the guage and hvac lighting on the dash to white LEDs. 1 headrest monitor is mounted in each front headrest. They show whatever is on the front PC screen except for the reverse camera and movies. Nothing changes on the headrests when backing up. When playing movies, the front touchscreen shows the dvd player controls and the rear monitors show the movie. The movie can also be seen in the front by changing the input from VGA to composite with the remote control. I have an unused input on each screen. I'm not really into video games, but that is an option. I am content with the audio system for now, but I will list what I have in case anyone wants to add opinions about it. 1 JBL px300.4 JBL c608gti components driven off front two channels of the amp. Mids are in the doors and tweeters are in the A pillars. 2 old school JBL GT 12" subs driven off the rear channels of the amp. These are 4ohm DVC running at 2 ohms on each channel. It's not a ton of power for the subs, but they are very efficient and seem happy with the power. All 4 doors + the hatch and floor have been deadened with edead. The floor and wheel wells also have a layer of jute padding to help with road noise. I am sure I have forgotten a few things, but that is the majority of it. I'm not really looking to replace anything. I would just like to add more features. I am not a pro at this, but I do all of the work myself just for fun. Keep in mind that I have the PC at my disposal, and I'm not afraid of relays, solenoids, diodes, or anything else of that nature. Any ideas that would help bring more luxury to my econo box would be appreciated. Thanks :)
