Works

A program that turns pasted source code into an image suitable for use in a report.

A utility that fixes the issue where AirPods reset their volume when connected to macOS.

I created an online multiplayer typing game using Next.js, Node.js, and Socket.IO. Players can compete with each other in real time over the internet.

A macOS transcription tool built with SwiftUI. It runs a Whisper model locally, records audio while a shortcut key is held, transcribes it, and inserts the resulting text.

An app designed to help users stay focused while reading by highlighting text one line at a time. It uses OCR to extract text from the camera and highlights sections separated by designated markers. Non-highlighted sections remain visible with reduced opacity. This project was selected as a Winner of the Swift Student Challenge 2026.

A faster version of my homepage built with Astro. Creating a Markdown file automatically generates a link to the page.

A page where you can view school assignments, events, and schedules in one place. After signing in, it retrieves data from Supabase and displays a list of items you need to bring.

A homepage built with Next.js and hosted on Vercel. It can generate pages from Markdown files.

RC Flow is a simple time-management tool I created to manage study sessions. After setting what you want to do today and how long each task will take, it displays work and break periods. It is designed to avoid interrupting concentration and to make work and breaks clearly distinguishable. It is available as a web app.

A tool that converts distorted 360° video into a single video made by stitching together six square videos. I built it for macOS in Swift. The tool splits the video into image frames, then uses trigonometric calculations to determine which pixel in the distorted source corresponds to each pixel in the flat output.

I created a cursor that follows the mouse as practice for C. When it approaches a button, the cursor smoothly morphs into the shape of the button, and I added animations that make the button label appear to move toward and follow the cursor.

A bot that notifies you about school assignments and events. It was built using the iPhone Shortcuts app. After registering assignments, events, and items from the Home Screen, a daily message is generated when the message-generation shortcut is run. The generated message is automatically sent every day at 4:00 PM.

Using my custom rendering engine, RC Tracing, I simulated a projector emitting light and projecting an image onto a wall. The light is emitted from the center toward the left wall, where it reflects diffusely. I added a smoke effect to the room so that the beam of light from the projector is visible.

RC Tracing is a rendering engine that renders from the light-source side, unlike conventional ray tracing. Rendering takes time, but it can produce realistic images. It is available from a dedicated website.

I created a 3D model of a searchlight in Blender. I recreated the type of machine used in nighttime theme-park shows and similar scenes, which projects a strong, narrow beam into the sky or an interior to create visible shafts of light. I added noise and stabilization effects to make the footage look more realistic.

A 3D rendering engine created in Scratch. It uses ray tracing to calculate which points in 3D space correspond to image pixels and generates an image through repeated processing.

A study-time management tool created in Scratch. It displays the day as a timeline and lets you visually set how much time to spend on each activity. To avoid distracting users while studying, the screen uses softer colors during study sessions.

A version of my homepage where page information could be managed in bulk using JSON.

The site I used from around autumn 2022 through 2023. It was the first version I published on the Internet using a free hosting service.

A game where more than 10 players can move around and chat together. Scratch only allows up to 10 cloud variables, but by sharing each player’s identifier, this project allows more than 10 players to join at the same time.

A simple platformer game where you control the player with the arrow keys and try to reach the goal. I created it as a JavaScript practice project. It can still be played on my old website.

A game where you can create your own sugoroku board and play on it.

A tool for easily running live streams in Scratch. It uses Scratch cloud variables to support simple live streaming, preset chat messages, movable on-screen sprites, and preconfigured slides.

A game where you move a player through a 3D space and try to reach the goal. I created it as practice for JavaScript.

A homepage I created during the summer of my first year of junior high school as practice for text-based programming.

A platformer whose stages are drawn using Scratch’s pen and stamp tools.

A 3D graphics program that allows movement and rotation at the same time using the arrow keys.

A game created to let you experience the feeling of traveling even during the COVID-19 pandemic.

A game where you pilot a Saturn V rocket on a journey to the Moon.

An automatic mopping robot built with LEGO EV3. When its infrared sensor detects a wall, the robot turns.

A game where you move through a 3D space and shoot enemies to defeat them.

I built a device that uses EV3 tracks to lift a LEGO roller-coaster car to the top.

A game where you control a cat with the arrow keys and try to reach the goal. It was the first programming project I published on the Internet.
