One Line Hilbert Cat Sunfade Zip-Up Hoodie

One line. It never lifts.

A Hilbert curve is a single line that folds back on itself until it fills a square without ever crossing. Seven generations deep, it passes through every part of the circle on the back. Where it runs through the cat it is drawn thick in green; everywhere else it is a hairline. So the cat is one continuous stroke, from the tip of an ear to the end of the tail.

The design

A fine sage-grey hairline, the cat traced in forest green, and rust eyes, across the back. Above it the Nekomori wordmark and Field Equations / No.07 One Line; below, 猫森 and the equation itself: A → +BF−AFA−FB+   B → −AF+BFB+FA−   n = 7. A small version of the drawing sits on the right chest, beside the zip.

The fit

Boxy and loose, with a dropped shoulder and a two-way zip, so it opens from the top or the hem. Take your usual size for the relaxed shape, or size down for a closer fit.

The sunfade finish varies from piece to piece, so the fading on yours will differ a little from the photos.

Color, Pattern & Material

Field Equations is Nekomori's series of cats drawn by mathematics instead of by hand: each design is a single equation, rendered, then left alone. It continues from Quiet Forms: Field Note 01.

Printed for your order in the USA — nothing is held in stock. Artwork original to Nekomori, generated from the equation printed beneath it.

Care

• Machine wash at 30°C / 86°F, gentle cycle, inside out
• Do not bleach
• Tumble dry low
• Iron at low temperature, never directly on the print
• Do not dry clean
