The name Lepton appeared on Steam and SteamDB just a few weeks after Valve unveiled the Steam Frame headset, which will be able to run Android apps.
In our new interview with Valve’s Pierre-Loup Griffais, he mentioned the Frame uses “a similar compatibility layer as Proton, just targeted at Android.”

I always enjoy recognizing a specific developer’s handwriting in a finished product. Luckily, Valve’s misyltoad, a proud inhabitant of “Frog Cult”, United Kingdom, makes this very easy. From their work on frog-fifo-v1 for Mesa, to frog-color-management-v1 and frog protocols for Wayland, to their talk Rainbow Frogs: HDR + Color Management in Gamescope/SteamOS, they seem to follow a very strong theme. I’d be surprised if they weren’t responsible for this frog as well.
They’re even wearing a 100 gecs - Frog on the Floor shirt in their Rainbow Frogs talk. (better view here)
