Show HN: Tkintergalactic - Declarative Tcl/Tk UI Library for Python

Summary

Tkintergalactic Declarative Tcl/Tk UI library for Python. Somewhat React-like (there is effectively a Tk VDOM). Well typed. Maps very closely to the underlying Tcl/Tk for ease of debugging. Zero dependency. On mac sometimes you have to start by wiggling the window. Small enough to understand how it works. In an incomplete state - much functionality missing.
