This was my dream shot for the "Centred" challenge, months ago, but 'cos you can't stretch or distort an image, I couldn't submit it. Anyway, since so many have recently done "in the corner" shots, I thought I'd put mine up as well.
There's more than one way to skin a cat, without exception. If the rules don't allow stretching and distortion, then a flexible mirror could have yielded a similar effect.
