This is really cool project if you like PC modding. So this is an USB interface for alphanumeric LCD display like 4×20 which can be controlled with LCDSmartie program.

USB interface is implemented by using PIC18F2550 microcontroller. Using USB LCD module you can view many types of information taken from PC like temperatures, time/date, MP3 song titles, view emails, RSS feeds – all that LCDSmartie or other program supports.
