## Description

CRUMB is an immersive 3D circuit simulator that serves as an educational tool and a prototype workspace for electronic development. It provides an easy-to-use, interactive introduction to electronics and lets you build circuits in a fully realized 3D environment, without risking terminal component failures or the hassle of sourcing parts.

It ships with a broad component catalog, enabling exploration from transistors and audio filtering to EEPROM programming. Beginners learn interactivity, while enthusiasts can analyze and refine prototypes before building real hardware. With built-in oscilloscope and analysis views, you can visualize interactions inside the wires. As the community contributes feedback, more components and features will be added.
