Tomáš Dvořák (born February 14, 1978), known professionally as Floex, is a contemporary Czech composer, clarinetist, producer, DJ, and multimedia artist. He is best known for his work with indie game studio Amanita Design.
Dvořák released his debut album Pocustone in 2001 under the moniker Floex, which is a combination of the words "float" and "experiment". His work came to wider recognition, however, after composing the soundtrack for Amanita Design's award-winning adventure game Machinarium, as well as the Samorost series.
