Here's a good way to waste 500 euros

Is actually putting metal into your eye even safe? It looks pretty interesting, not that it's worth it.

Eventually people are going to run out of external body parts to jam metal into. I predict that eventually the fashion trend will turn to internal body parts; like you can have a big plug of your abdomen wall taken out and replaced with a transparent piece of glass or plastic so people can see your guts.

That made me think of computer chassis with transparent windows that are jammed full of LEDs and disco-light processor fans, that people sometimes bring to a LAN. And I think that's dumb too.
