Three steps to an extra-spooky Halloween

1. Get a child-size Grim Reaper costume.

2. Add evil pulsating LED eyes.

3. Mount it on a Roomba.

Your specter will now careen drunkenly down your office hallway, slamming into walls and spinning around like an idiot. Beware the Grim Sweeper.

When my partner in spookiness left Apple, I made him a baby Sweeper, to sweep his desK and remind him of the spooky times we had.
