The Prysamids are a continuation of Chais' "Prisms" that have evolved into three dimensional pyramid hybrids. They continue to refracts light like a kaleidoscope creating new visions and also have either sculptures or films inside.

The nature of a prism transmits both reflective and transparent light. The viewer can see through it but it also mirrors one's image. The multiplicity in perceptions becomes malleable. The pyramid shape references the Ancient Egyptian architecture that serves also as a tomb for the body where the soul returns to visit. 

The inner "walls" of each "Prysamid"  contain abstracted images manipulated on the computer. They may encompass landscapes, geometric forms, texts projected onto luminescent or film screen sheets.
