Skull Flower

I don't remember where I found this image, but I do find it quite lovely for so many reasons.

Yo La Tengo - Green Arrow

And I find this song lovely as well. Good for a peaceful mood on a peaceful night... Where you are sitting around thinking of nothing in particular and just wanting to feel a sort of serenity about yourself.

Theo Twist

This artist is adorable and great for a nice, bubbly, feel-good mood! This song is also highly addictive if it happens to be your style ...

A Fine Frenzy - Electric Twist

This is a video I found on TED a while back. Theo Jansen is a dutch artist who makes quite the interesting kinetic sculptures. I love art and science, so I think his work is just fantastic.
