Jaguar on the Gym Wall- 適合中高級的英語短篇故事

Marcos knelt near the back wall of the quiet gym, holding a palm-sized projector cube. He had spent three weekends soldering wires, attaching a tiny edge computing board, and polishing its transparent cover. Many classmates had called the design innovative, yet tonight he aimed to prove it worked outside his bedroom. Inside the cube, an algorithm converted sensor readings into swirling beams of color. A high-performance micro fan kept the circuits cool, and a cutting-edge light chip waited for power. Marcos pressed the switch; faint whirring answered. He angled the lens toward the empty stage, hoping the first pattern would cross the curtains.

The image flickered, then vanished. A loose HDMI extension had slipped from the laptop, pulling the cube sideways. Marcos steadied it, but the cable remained stubbornly short; if it had reached a little farther, the test would have started sooner. He dragged a chair forward, raised the laptop, and tried again. This time the colors appeared, yet spiraled wildly because the gyroscope data had been read backward. Marcos’ shoulders lifted and fell as he rewired two pins under the phone’s flashlight. Three minutes later shapes finally stabilized, forming an unexpected silhouette of the school’s jaguar mascot across the wooden floorboards.

Footsteps echoed at the entrance; the theater crew had been delayed by a rehearsal note, so nobody had seen the earlier chaos. They gathered now, pointing at the giant jaguar that prowled across the stage curtains. One voice called the accident brilliant, believing the image intentional. Marcos wished he had prepared such a surprise on purpose, but his grin stayed hidden behind the glowing cube. The battery icon blinked red; a power bank clicked into place, and the fan whirred again. Light pooled over the gym wall while the cube rested beside a silent ladder.

Marcos 半跪在安靜體育館的後牆邊，手裡拿著一顆掌心大小的投影方塊。他花了三個週末焊接線路、裝上小型邊緣運算板，還把透明外殼擦得晶亮。許多同學說這設計很創新，但今晚他想證明它在臥室外也能運作。方塊內的演算法把感測器讀值轉成旋轉光束，高效能微型風扇維持電路冷卻，最尖端的光源晶片靜待通電。Marcos 按下開關，微弱的嗡嗡聲響起。他把鏡頭對準空舞台，希望第一道圖案能掠過帷幕。

影像閃了閃就消失。鬆脫的 HDMI 延長線從筆電滑出，方塊跟著歪向一旁。Marcos 扶正裝置，但線仍嫌過短；如果線再長一點，測試早就開始了。他把椅子拖來墊高筆電，再次啟動。這回雖然出現顏色，卻因陀螺儀資料方向顛倒而旋轉失控。Marcos 在手機手電筒照射下重接兩根針腳，肩膀一起一落。三分鐘後，圖形終於穩定，竟在木質地板上形成學校吉祥物美洲豹的輪廓。

入口處傳來腳步聲；劇團因彩排通知延誤，沒人看到先前的混亂。眾人此刻圍觀，指著在舞台布簾上徘徊的大型美洲豹。有同學稱這意外很精彩，以為是刻意安排。Marcos 真希望自己原本就設想過這驚喜，但他只是站在發光方塊後暗暗露出笑容。電池圖示閃紅，他接上行動電源，風扇再度嗡鳴。光束散落在體育館牆面，方塊靜靠在無聲的梯子旁。
