What to do with 22,000 business cards?

Yes, I'd say she's obsessed.

Obsessed with Hobbits!

This man has painstakingly created a miniature replica of Frodo's Hobbit House. Must be seen to be believed!

Darth Vader OCD

These people must be huge Darth Vader fans. HUGE.

Master of the Etch-a-Sketch

This man has truly mastered the ancient art of Etch-a-Sketch. There's a link to an interview with the man here where he shares some of his secrets, talks of preservation (fear of earthquakes, perhaps?), etc.

Paintings on Walls

These paintings on walls are just incredible. The attention to detail is astounding. Do have a look.

Fans for Life

These people have dedicated their bodies to show their love and admiration to their favorite video games. You have to be obsessed over a video game to do this, I think.
