I know of a few painting tools for fun in VR, but what I’d really like is animation.

I spent a lot of time animating keyframes in Garry’s Mod, though it’s sometimes a struggle to translate positions and rotations into mouse movements, as well as think about a wealth of tools that can only take up so much space on the monitor.

If there’s a way to create character animations using VR hands, that might really interest me.

Mine is not arrived yet so I cannot say if any of these works on the Frame standalone nor if it runs on Proton. But here are the free games/experience I enjoyed when I started VR. Order is kinda from fav to least but not really.

FREE

• The Lab
• Adventure Climb
• ART Plunge
• OpenBrush
• theBlu
• aircar

As a bonus here is a list of games that are very cheap on sale and that I enjoyed. Remember these were NOT tested on a standalone headset nor a GNU/Linux OS!

CHEAP and worthy – Usually less than $5 when on sale

• SUPERHOT VR
• A Fisher Man's Tale
• Keep Talking and Nobody Explodes
• Traffic Jams
• Panoptic

I know there's IKEA Pancake Kitchen, which is unavailable in Germany for some reason.

There were some Spider-Man games as promotions for the movies, but they have been delisted. The one I have wouldn't launch standalone anyways.

If we ever get a working WebXR browser there are a ton of browser games like https://spiderman.webvr.link/ and https://moonrider.xyz/.

I have successfully started Star Wars: Droid Repair Bay. There is also Trials on Tatooine which I haven't tested yet.

SideQuest also has a shit ton of free games. Most are for the Quest, but they may also work with Lepton. I have only tested Minecraft VR so far and that worked halfway (the game started but actual Minecraft did not start).

I'd have to look it up but there's an older one that lets you virtually tour an Egyptian tomb. Ah, here it is https://store.steampowered.com/app/861400/Nefertari_Journey_to_Eternity/

Well I'd like to but I'm on the waitlist. >:(

I don't know if it runs on the Frame, but Google Earth VR is a very fun free VR "game".
It's pretty cool just walking around anywhere in the world in decent quality.

Tilt Brush - Draw in 3D

Blocks - Simple 3D modeling

Still waiting on mine but I bet Aperture Desk Job would be fun. Try it and let me know.

I'd be interested to see what free Android/Quest APKs work, as that's the big unknown here. Windows and Linux apps should work the same as they do on SteamVR on a Linux PC, excepting the Frame specific ports and performance differences.

Another one:

Standalone - A Shopping Trip to Eklan Tor - amazing little game, very cool experience for someone new to VR. Simple low-poly graphics, but a very intricate little interactive environment for someone to explore in VR, like a very elaborate doll house or doll village. I've always been fascinated with miniatures, so it's right up my alley. The controllers displayed in the game are a bit messed up and I noticed some aliasing or something (it may just be my settings, I need to check the articles/videos for the ideal settings) but it's still very much worth it.

The three that I've listed so far (Arcturus Vision, BoomXR, and Eklan Tor) seem like very good free options to demonstrate VR to someone. None of them have any locomotion, so it should keep any chance of VR sickness to a minimum if not eliminate it completely.

Not quite free and might not work standalone, but I adore BLARP!
