A bit of Escher inspiration combined with the handy iPhone camera…
Given the largest sized file you can get from your iPhone 6, you could make a 300dpi/ppi, 8×10-inch, print from this. Yeah, they are jpeg–not raw–files, but you can make some adjustments. (Among other things, I ran this one through Nik/Google Color Efex Pro’s Tonal Contrast filter.)
Not bad for a goofy little 8-megapixel camera that’s with you everywhere you go!
