Interactive tools

Concepts you can poke at.

Computer science is easier to feel than to read. Every tool here makes one idea tangible — move a slider, watch the visual and the code change together. Built from books and curiosity, one concept at a time.

The bigger map

Where this is going

The lab aims at the whole of computer science, not just the parts that are filled in yet. Here's the full map — what's live, and the blind spots still waiting for a tool.

Frontend & Design

CSS, layout, colour, type and motion — the visual craft of the browser.

10 live

Programming Foundations

How code actually runs: variables, types, control flow, functions, async, OOP.

8 live

Algorithms & Data Structures

Sorting, searching, Big-O and the data structures underneath them.

Coming soon

Databases & Data Modeling

Modelling data and querying it: SQL, joins, indexes, transactions, NoSQL.

8 live

Data Science & Statistics

Wrangling and understanding data: DataFrames, distributions, statistics, ETL.

5 live

AI & Machine Learning

How machines learn and generate: training, neural nets, transformers, RAG, agents.

69 live

Computer Systems & Architecture

What's under the language: bits, memory, the CPU, GPUs, how machines store data.

1 live

Networking & The Web

How the web moves: HTTP, DNS, TCP/IP and what the browser actually does.

Coming soon

Operating Systems & Concurrency

Processes, threads, scheduling and the art of doing many things at once.

Coming soon

Security & Cryptography

Hashing, encryption, keys, guardrails and the common ways software gets broken.

1 live

Math & Theory

The maths behind it all: linear algebra, probability, logic, discrete maths.

7 live

Software Engineering & Tools
