When it comes to video game motifs making the leap from screen to accessory, Space Invaders has everybody beat.

Whether they're on a minidress [1], an ice cube tray [2], or even a cutting board [3], the pixelated characters remain a favorite.

The gold Space Invader Necklace [4] by Han Cholo [4] is a logical transition — it was only a matter of time before someone cast it in a precious metal (and yow, asked $165 for it).

I guess it would be great for your most formal geeky events, right?
