Dream: an animation in Ruby
summary
A four‑minute music video called Dream gets built with Ruby using the gamebox gem on top of Gosu, plus the tween gem for eased motion; assets are pixel art sprites and sprite sheets, layered with timers to create retro parallax scrolling. Audio takes about a month, animation another month, final mix compresses from ~150MB to 6MB. A premature 640x480 startup mistake breaks widescreen alignment, an offscreen buffer attempt produces video noise, but the animation pipeline and tweens otherwise work (demo has audio hiccups).
