I've always wanted someone to make a place like this.

Periodic Table Displays.

It's just like a regular periodic table, 'cept it contains a real life example of the element.

Definitly appeals to the geek in me.

I love the little warning sign on the radioactive elements "This unavailable element is represented by a radiation hazard symbol. If we had a visible quantity on display here, you would be dead."
