Description: A completely official seal of haunting, issued by no one, backed by nothing, and accepted everywhere. For anyone whose house creaks at 3am, whose ghost hunting show is on in the background, or who just really likes a cheerful little ghost. Wear it, stick it on your laptop, or apply it to a room that has earned the designation.

Description: A heisenbug is the bug that vanishes the moment you try to observe it runs fine in the debugger, breaks the second you look away. Every developer has lost an afternoon to one. A gift for the programmer, software engineer, or CS student in your life who has said "it works on my machine" with a straight face.
