[1] Tzivelos' early works included in situ three-dimensional autoluminous installations and experiments with painting on glass.

[3][4] In 2018, a retrospective exhibition of his work titled, Modeling Phenomena, was held at the Benaki Museum Annexe in Athens.

The show focused on Tzivelos' light work from 1977 to 1995, that have been described as "poetic and highly meditative" and influenced by his interest in "Greek mythology, philosophy, alchemy and cosmology.

"[5] Tzivelos also created works using projected light that were grounded in the notion of "coinciding opposites" as proposed by Heraclitus such as presence/absence, light/dark and beginning/end.

These ideas also informed his works "Light-Fossils", round-shaped drawings which were exhibited in his final solo show in 1993.
