The prompt
Claude · Claude Opus 5.5
Create a star background animation for a launch countdown. Full-screen canvas on an almost black page (#02030a). Stars fly toward the viewer from the centre in perspective, drawn as short streaks from their previous position to their current one, getting brighter and thicker as they get closer. Tint them white, cyan (#a5f3fc), lavender (#c4b5fd) and pink (#fbcfe8). Use about one star per 800 square pixels, up to 1,400. Normal speed is a calm drift; pressing and holding anywhere, or holding the space bar, smoothly accelerates to nine times faster with long light-speed trails (paint each frame with a semi-transparent background instead of clearing it), and letting go slows back down. Moving the pointer gently shifts the vanishing point for a parallax feel. Centred on top: an extra bold white headline "Launch week starts in 3 days" with "in 3 days" in a cyan to pink gradient, and the hint "Press and hold anywhere to jump to light speed". Scale for retina and stop the animation for reduced motion.

About this star background animation
A star background animation is the classic way to make a launch feel like a departure. Here stars stream toward you from the centre of the screen, small and dim in the distance, then brighter and longer as they pass. Press and hold anywhere, or hold the space bar, and the field accelerates into long light-speed trails; let go and it eases back to a calm drift.
The trails come from a simple trick: instead of wiping the canvas each frame, the page paints a semi-transparent layer of night sky over the last frame, so fast stars leave streaks behind them. A slight shift of the vanishing point as the pointer moves adds depth without any 3D library.
Why the prompt works
It explains the drawing method, streaks from the previous position to the current one.
It sets the density and the cap, so phones are not overloaded.
It defines the interaction, hold to accelerate, release to slow, with a keyboard option.
It gives the trail technique in one sentence.
Where to use it
Launch pages, countdowns, event sites and space or science themes. Pair it with one short, bold line of text.
