This is an Atari 2600 emulator that can stream the video over a network, currently using VNC or alternately as a stream of GIFs to a web browser.
Using some PHP and Python code on a webserver, it can be set up using Kubernetes so a web browser can pick a ROM to play and the game will be launched on a node in the Kubernetes cluster and be playable in the browser.
