Sloan Digital Sky Survey Visualizer

A 3D visualization of the universe you can explore, built from 150,000 galaxies in the Sloan Digital Sky Survey. Drift through 2 billion light-years of space and reveal the cosmic web — the vast filaments and voids that form the large-scale structure of the universe, mapped from the Tempel et al. (2014) filament catalog. Tap any galaxy to see its image and data.

Fireflies

A simulation of firefly flash synchronization in Photuris frontalis, the synchronous firefly of the southeastern United States. 171 brightest stars positioned using real J2000 coordinates, transformed to your local sky based on date and approximate coarse, IP-based region.

PulseCam

A browser-based heart rate monitor that measures your pulse in real time using your device camera and remote photoplethysmography (rPPG). No physical contact required. All processing is on your device. No data leaves your phone.
