TimeCapsuleLLM

The first ever language model pretrained on historical texts, trained using only data from 1800–1875. TimeCapsuleLLM began in July of 2025, and has since evolved into a collection of language models and datasets. The project started completely independent but has since been under academic collaboration with several institutions.

Repository Models & datasets

Lego Mosaic Motion

Animated LEGO-style mosaic generated from a video clip

A browser-based tool that turns short video clips into LEGO-style mosaic motion pieces — not a filter, every frame is converted into an actual brick mosaic. Crop, scale, and recolor your shot, then export a motion video or a full project bundle with piece lists. Not affiliated with The Lego Group.
