...You can attach these gadgets to your hands and bring them with you in your favorite VR apps. If you just want to make gadgets, your best bet is to use a released build. Just download and run the latest released installer, then run aardvarkxr.exe from the install directory. Once you've installed you can also enable Aardvark to start automatically in the Startup/Shutdown settings in SteamVR. Aardvark is made up of "gadgets". These are 3D objects that do something useful, something fun, or maybe they just look cool.
