In the first part of his career as a singer (1989–1995) he was famous for wearing a commedia dell’arte-style clown mask, covering half of his face only.

The concept, scenario, game design, 2D graphics, sound and music have been Pierrot’s personal fields of responsibility from the start.

This FMV (full motion video) game won first prize at the Hungarian eFestival 2007 in the category of interactive storytelling.

[6] The most outstanding manifestation of his passion for Chinese culture was his planned video game AGON: The Tales of the Four Dragons.

Pierrot has been a productive composer and music producer, creator of dozens of Hungarian top hits performed by other singers as well as himself.

In 1991 he composed music for the Hungarian stage adaptation of Anthony Burgess’s Clockwork Orange and had regular multimedia-based performances in Budapest’s traditional Bábszínház puppet/marionette theatre.

[7] He had been producer and many times composer of several albums for other Hungarian performers including Ganxsta Zolee (hip-hop) who also appears in Pierrot’s video game Yoomurjak’s Ring and lends his voice to certain characters in AGON.

The title music of Yoomurjak’s Ring, Coming Back Home is one of them, co-written with Jamie Winchester, the singer of the English version.

As an enthusiastic collector and reviewer, he launched a multilingual online adventure game magazine titled Inventory.

[8] In 2005 Pierrot and his team were entrusted with creating a video game as an unconventional means of promoting the tourist attractions of Eger, a Hungarian town with a considerable historic background.

[9] Yoomurjak's Ring was based on a popular Hungarian novel written by Géza Gárdonyi in and about Eger in 1899.

[11] Under his real name Tamas Z. Marosi, Pierrot was co-author of a Hungarian rock music manual covering the eras 1950-1993.

As a fan of Asian culture, he was the author of a book on the gastronomy of India, China, Indonesia and Thailand.

[12] Upon the success of the game Yoomurjak's Ring Pierrot launched a series of novels under the title Jonathan Hunt Adventures in 2011.

[13] Pierrot presented 24 of his own classic abstract strategy board game illustrations in a large, playable album in 2011.
