Casa Serra: A House Built From a Floor Plan

A flat floor plan becomes a full house as you scroll. This project, called Casa Serra, renders a detailed building directly in your browser without loading a video file. Instead of showing a static image, the page draws the walls in real time using code. As you scroll down, the camera moves from the top view of the blueprint into the actual rooms. The architecture appears to rise from the paper, turning lines into solid walls and floors. This is interesting because it turns a simple document into an interactive space. The creator used about seventy prompts to refine this effect over two weeks.

Toks: The Fastest Tokenizer You've Never Heard Of

Toks is the tokenizer that actually respects your hardware's speed limits. Every time an AI model reads text, it breaks words into tiny chunks called tokens, and most libraries are slow to do that math. Toks fixes that by running the exact same tokenization logic at the absolute maximum speed your processor allows, ensuring you get identical results without the usual wait time. It supports major models like Llama and Gemma, proving that speed and accuracy do not have to fight each other. If you are building high-performance AI tools, this is the drop-in replacement that keeps your data moving as fast as your silicon can handle it.
