Contemplating a tattoo

…someday. And so here're the ones currently under consideration:

• Two ravens, along with a quote from verse 80 of Hávamál: "Praise ice when over it". (But ideally, translated into Icelandic.)
• This — the cherry blossom eight-sided mirror symbol of Kodokan Judo.
• Eppur si muove — Galileo's (probably apocryphal) rebuttal to his forced confession that the Earth does not move. It means "And yet it does move."
• "Luminous beings are we, not this crude matter".
