Epicycles Cat Boxy T-Shirt

A minimalist cat t-shirt and a nerdy gift for cat lovers: a sitting cat drawn in one green line by ninety circles turning at once, on the back of a boxy 400 gsm heavyweight tee in white, apricot or oat gray.

A cat, drawn by ninety circles turning at once.

Any closed shape can be traced by a chain of circles, each spinning at its own speed on the rim of the last — astronomers called them epicycles long before anyone drew a cat with them. Here a sitting cat is broken into ninety of them. The print stops the machine four-fifths of the way round: the chain of circles still in place, the pen still on the line, the last stretch of the cat only dotted in.

The design

One thick forest-green line for the cat, fine charcoal and sage circles for the machinery, and rust arms joining them to the pen. Nekomori wordmark and Field Equations / No.03 Epicycles above; 猫森 and z(t) = c₀ + Σ c_ke^{2πi f_k t} below. A small version on the left chest.

The fit

Boxy: wide and square through the body, dropped at the shoulder. A dense 400 gsm cotton that stands away from the body instead of clinging.

The blank

• 100% cotton, 400 g/m² (11.8 oz)
• Boxy, oversized cut with dropped shoulder
• Sizes S–2XL
• Printed with DTF (direct-to-film) transfer

Giving it as a gift

A gift for the cat lover who likes things that are cleverer than they look. From a distance it's a simple line-drawn cat; ask how it was drawn and the answer is Fourier epicycles. The dense, boxy heavyweight cotton suits anyone into streetwear cuts.

• Sizing for someone else: It's boxy and wide with a dropped shoulder, so their usual size gives the square shape shown. Sizes S–2XL. If it doesn't fit, it can come back within 30 days of delivery, unworn, with free return shipping.
• Ordering for Christmas or a birthday: every piece is printed after it is ordered, so count back about three weeks and order before then. The dated delivery estimate under the buy button is the one to go by, and checkout offers express shipping on most garments if you are cutting it close.
