An Ergastulum is a building used to hold in chains dangerous slaves, or to punish other slaves. The Ergastulum is subsurface and large enough to allow the slaves to work within it and containing narrow spaces in which they sleep. Currently in development for Vive and Oculus Rift.
Here is a re-imagination of the legendary Mothman. It is made up by hundreds of... Moths! ;)
Each moth is animated by a shader and works quite well.
