Interesni Kazki (IK) is Aleksei Bordusov and Vladimir Manzhos, a duo from the Ukraine who also go by their respective aliases AEC and WAONE. They began working together in 1999. They were the precursors of the graffiti movement in the East European countries and since then, these guys have created many murals in the Ukraine and Russia  and in countries all over the world, in their distinctive narrative and symbolist style. 
Aleksei and Vladimir are inspired by themes such as science, religion, cosmology and social subjects, though they usually make work with free meanings that everyone can interpret on their own.
