How to give yourself a heart attack in three easy steps:

1. Spend more than an hour playing with pictures, making a new design.
   
2. Finally put it all together into the mock-up, delete all the altered images that went into it, and sit back to admire your handiwork before you save it.
   
3. Blue Screen of Death.

(Fortunately, it wasn't PSP having the BSD, but my email, and everything was all right.)
