Just spent the last weekend doing my first Arduino project.
I'm using an LCD and a real time clock to display a "one time password" for my google account (more on that here: http://googleblog.blogspot.com/2011/02/advanced-sign-in-security-for-your.html)
I've got it all going on a breadboad. The next step would be getting it into a neat box with a battery I can put on my desk. Not sure where to start. Do I buy a protyping shield for the UNO and put the LCD + RTC onto that? Getting a PCB printed is way beyond me. Just after the easiest solution to make something neat.
