Start at the burst of rainbow in the lower center part of the picture, and follow its curve up and to the left to see a helmet above the rider's brightly lit shoulder, arm extended forward. But wait, isn't that an arm below and behind his helmet? Does that belong to someone sitting behind him? ...or is that a ghostly helmet in the clouds above and behind him? Are they motorcycle helmets, or spacesuits, or ...? Then again, step back, maybe that's his nose, not his arm, above his lips, his eyes in the space between what looked like his helmet up close ...
Ah, clouds - where stories are only limited by imagination ...
