I will create a physics or math animation computed from real equations
tsmat
About this gig
Physics animations that are actually right.
I build 2D physics and math animations from the real equations, not from keyframes or AI video generators. If the screen says 314 collisions, the simulation really counted 314.
I have made over 180 of these for my own science channel: collisions, pendulums, orbits, waves, light, probability, chaos, fractals and more.
What you get:
A custom animation of your idea, 16:9 or 9:16
1080p at 60 fps, smooth motion
Clean on-screen numbers and labels, or no text for your own edit
Original background music I make myself (optional)
The key numbers checked against the math before delivery
Good for: science YouTubers, teachers, online courses, explainer videos, presentations.
Not a fit: 3D scenes, realistic water or smoke, characters, voice-over.
Please message me before ordering and tell me what you want to show. I will tell you honestly whether I can do it well.

I make 2D physics and math animations where the numbers are real. Every animation is computed from the actual equations and checked against theory before it reaches you. I run a science channel with over 180 of these videos: collisions, pendulums, orbits, light, probability, chaos and fractals. I work with science creators, teachers and course makers who want visuals that look good and are correct. Based in Japan.
FAQ
Can you animate my topic?
Probably, if it is 2D and follows known equations: mechanics, waves, light, orbits, probability, geometry, simple biology models. Message me first and I will tell you honestly.
Is the physics really accurate?
Yes. The motion comes from solving the equations (exact collision events, numerical integration or closed-form formulas). Before delivery I check the key numbers, like collision counts or angles, against theory.
Do you use AI?
The motion comes from my own simulation code solving the real equations. I do not use AI image or video generators. I use AI coding assistants to write code faster, and every result is checked against the math.
Can I use it commercially?
Yes. You can use the delivered video anywhere, including monetized YouTube and paid courses. The music is made by me, not taken from a library. My simulation code stays with me.
Can you match my text, colors and style?
Yes. Send your wording, brand colors and any examples. Text can be English or Japanese, or I can deliver it with no text so you can add your own.
Do you do voice-over?
No. I deliver the animation with music and sound effects. If you will add narration, I can leave pauses where you need them and send a list of timestamps.
What file do I get?
MP4 (H.264), 1920x1080 or 1080x1920, 60 fps. A textless version is available on request.
