Live experiments

Fourteen sketches, one shared graph

• Graph Signal Diffusion

  Inject a signal into one node and see how local neighborhoods carry it.

• GNN Message Passing Toy

  Choose node features, stack message-passing layers, and watch embeddings smooth over edges.

• Clustering Lab

  Add points in 2D, compare clustering algorithms, and tune the grouping assumptions.

• Gravity Assist Sandbox

  Launch a probe through a miniature solar system and use flybys to reach a target planet.

• Fourier Transform Playground

  Add sine waves one at a time, hear the mixed sound, and watch the spectrum change.

• Signal Filter Playground

  Try classic signal filters on simple tones and compare input, output, and frequency response.

• MLP Decision Boundary Lab

  Customize a tiny neural net, switch activations, and watch its learned boundary change while it trains.

• Diffusion Model Denoising Toy

  Add noise to a generated image, then step backward through a simplified denoising process.

• Convolution Kernel Playground

  Edit custom 3x3 and 5x5 image kernels and compare the original and convolved image.

• Image Color Editor

  Load or generate an image, shift its colors, swap RGB channels, and save the edited PNG.

• File Converter

  Convert images, audio, and video locally with browser-native tools and FFmpeg.wasm.

• Anomaly Node Game

  Watch a dynamic graph and identify the node that reacts differently.

• Computer Vision Mini Lab

  Small visual toys around detection, saliency, reconstruction error, masks, and image intuition.

• Circle of Fifths Network

  Explore keys, relative minors, and harmonic neighbors as a graph.
