This is a Cao demonstration where you can create tools for your own applications, link your OpenStar application to Cao, or add features to Cao . These examples are 100% free: you can use them and integrate them into your application without citing the source (unless you wish to). To export your tools, simply export the sprite named “Tools Wallpaper” (which you can rename). The rest is already in OpenStar and compatible with this format. Note from @The_OpenStar_Project : You must have the Home or Community version (not the Lite ones) to get this feature. And Wallpaper tools isn’t embedded in OpenStar.
