Make a sparkly t-shirt that sparkles with real lights.  The lights are triggered by the Circuit Playground's shake sensor, so they twinkle when you move, dance, jump, or wiggle.

This is a very easy beginner project that's great to do with kids.  It uses a vinyl cutter for the customizable iron-on decoration, and a Circuit Playground programmed with MakeCode, Microsoft's drag-and-drop code editor.  The electronics slip into the t-shirt pocket -- there is no soldering or sewing required.

Best of all, the Circuit Playground is removable, so you can easily use it for other projects too.
