This is an illusion scarf for my son - he and I are both big Nine Inch Nails fans (I listen to Ghosts every day!), so when I found this pattern on the interwebs, I knew I had to make it for him!
The design includes The Presence (a hand reaching out), and the NIN logo in the middle, and another hand on the other side. In Trent's song 'My Violent Heart' on the The Fragile album, the hand image is encoded in a spectrogram within the music! VERY cool. You can even download a whole new NIN album for free - The Slip is Trent's thank you to his fans. It's brilliant...
Anyway - the pattern is here (PDF link). Son chose the colours - both are Naturally yarn from NZ. I think it would be a bit clearer if we'd been able to get pure black for the contrast colour, but the dark grey seems to work OK, and the hidden image certainly is visible at low viewing angles!
I have a hand-drawn but gridded colour chart which I'm happy to scan and email people (the one in the pattern isn't so easy to read, so I drew a new one up).
