3D "what if" backyard
A 60 to 75 second 3D Short: a yard cut open like a cake while a narrator builds something.
git clone https://github.com/Theoxmotion/whatif-3d-studio mkdir my-video && cp whatif-3d-studio/whatif_guide.md my-video/CLAUDE.md cd my-video && claude Make one video. You pick the topic.
Details
Claude Code writes the script, voices it on your computer, builds the yard in Blender (free) and adds captions. About 2.5 to 3 hours on a gaming PC, mostly unattended.

Second-person survival stories in parts, flat stickmen in 3D rooms, ending on a comment vote.
git clone https://github.com/Theoxmotion/story-video-studio mkdir my-story && cd my-story && claude Paste the whole of story_video_prompt.md, then answer "you pick" at each step.
Details
Every frame is code, no AI images or AI video. Claude works alone for 1 to 2 hours. Listen once before you post.

Lecture explainer reel
A 45 to 60 second reel: a cartoon teacher talks while titles land on the exact word.
Make a 45 to 60 second vertical lecture reel about [YOUR TOPIC]. A cartoon teacher drawn in code talks in the bottom right corner. Titles, cards and tick or cross stamps appear on the exact word the narrator says. Use a free voice that runs on this computer, word-level timing for captions, and render to 1080x1920 MP4. Show me the script before you animate.
Details
Based on @finnardley's public lecture prompt and Theo's rebuild. This starter is written by Starbelo.

UI motion reel
One shape morphs through 8 to 12 UI states while a cursor clicks, cut to a 120 BPM track.
Build a vertical motion design video entirely in code (no After Effects). Ask me for 8 to 12 UI states the shape should become (for example button, loader, player). One shape morphs from state to state while a cursor clicks each change. Cut every change to a 120 BPM track I will download free from Mixkit. Render to MP4.

The full template is free in @twoclipping's Sep 24 post. This short version is in our words.

Make a 30 second vertical explainer: what if [YOUR WHAT IF]? Flat, colourful space style with a WebGL Earth and a small astronaut mascot, all drawn in code. Narration timed to the word. Use my ElevenLabs key if I give one, otherwise a free local voice. Render to MP4.
