Seamless patterns work best: tiles whose left edge flows into the right edge and top into bottom, so the repeats don't show on the figure.

• A square image of at least 800 × 800 px looks sharpest.
• PNG or JPG. Free seamless tiles are easy to find by searching for "seamless pattern".
• A picture that isn't seamless still works, but you'll see a line where it repeats.
