{"product_id":"arnolds-cat-cat-map-chaos-physics-t-shirt","title":"Arnold's Cat – Cat Map Chaos Physics T-Shirt","description":"\u003cp\u003eArnold's Cat gets sheared into stripes, scrambled into noise and then, on a 124×124 pixel grid, snaps back whole after exactly 15 steps. The map (x, y) → (x + y, x + 2y) mod 1 stretches by a factor of about 2.618 each step and squeezes by 0.382, so area is kept while the picture turns chaotic. On a finite grid no pixel is ever lost, only moved, so the shuffle must repeat. Arnold's Cat on a pixel-art unisex tee; equations, symbols and sources in the panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"S \/ White","offer_id":50913873952871,"sku":"20871099428214396403","price":29.99,"currency_code":"USD","in_stock":true},{"title":"S \/ Black","offer_id":50913873985639,"sku":"28232316689424565161","price":29.99,"currency_code":"USD","in_stock":true},{"title":"M \/ White","offer_id":50913874018407,"sku":"11563704755987410656","price":29.99,"currency_code":"USD","in_stock":true},{"title":"M \/ Black","offer_id":50913874051175,"sku":"29034265225476504754","price":29.99,"currency_code":"USD","in_stock":true},{"title":"L \/ White","offer_id":50913874083943,"sku":"29131126288357576046","price":29.99,"currency_code":"USD","in_stock":true},{"title":"L \/ Black","offer_id":50913874116711,"sku":"16717287507378021705","price":29.99,"currency_code":"USD","in_stock":true},{"title":"XL \/ White","offer_id":50913874149479,"sku":"27858861763286354088","price":29.99,"currency_code":"USD","in_stock":true},{"title":"XL \/ Black","offer_id":50913874182247,"sku":"32321008425642856689","price":29.99,"currency_code":"USD","in_stock":true},{"title":"2XL \/ White","offer_id":50913874215015,"sku":"32710396829939875264","price":29.99,"currency_code":"USD","in_stock":true},{"title":"2XL \/ Black","offer_id":50913874247783,"sku":"31475973738577713950","price":29.99,"currency_code":"USD","in_stock":true},{"title":"3XL \/ White","offer_id":50913874280551,"sku":"26228707207508062031","price":29.99,"currency_code":"USD","in_stock":true},{"title":"3XL \/ Black","offer_id":50913874313319,"sku":"20174020602458628430","price":29.99,"currency_code":"USD","in_stock":true},{"title":"4XL \/ White","offer_id":50913874346087,"sku":"35884912154280454721","price":29.99,"currency_code":"USD","in_stock":true},{"title":"4XL \/ Black","offer_id":50913874378855,"sku":"11144725582945588840","price":29.99,"currency_code":"USD","in_stock":true},{"title":"5XL \/ White","offer_id":50913874411623,"sku":"19285362782488893618","price":29.99,"currency_code":"USD","in_stock":true},{"title":"5XL \/ Black","offer_id":50913874444391,"sku":"89662946512430088207","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/arnold-cat-map_front_01_white.png?v=1793582035","url":"https:\/\/pixelatedphysics.com\/products\/arnolds-cat-cat-map-chaos-physics-t-shirt","provider":"Pixelated Physics","version":"1.0","type":"link"}
