The passenger - Iggy pop

Nickelback- Someday

We're Not Gonna Take It

Los Juegos del Hambre: Sinsajo Parte 1 - Trailer Oficial

Adafruit project - Led Eye Prosthetics

I've choose this project, ley eye prosthetics. In this video to see how it's done and more or less i think it's lenses with leds. It seems not very good health but in the use for robots could be well.
It's basically a head torch.

Metallica. Fade to Black

In this post I'll post a very good song by Metallica, Fade to Black subtitled both in Spanish and in English.

The video I've chosen has a good instrumental

Hope you like
