I've just finished converting the FriBuMet Day skin to 640 x 480. I've kept the fonts big enough to use on a small (7") screen. I'll finish the night skin soon too. I've no way of hosting them, so if anyone can then please let me know and I'll get the files to you.
The examples shown have a Porsche logo - the screen I use fits in the 944 centre console just perfectly. I've mounted the PC behind this so it doesn't take any valuable boot space. I'll get some pics of the install eventually for anyone who is interested.
