A regular contributor to the British website B3ta since 2004,Cyriak displays a surreal, psychedelic animation style, based on fractal geometry and orders of magnitude, often with a distinct British theme. Many of his animations are based on A-List celebrities, television shows and his hometown of Brighton. Cyriak's work has recurringly featured cats, cows, and sheep, among other themes. He has noted on his personal YouTube page that he uses a combination of Adobe Photoshop and After Effects for his animation and visuals along with Image-line's FL Studio for the original electronic music compositions that accompany many of the videos.
Cyriak's YouTube account features a compilation of his animations, which have been popular throughout the blogosphere and noted by Wired's Eliot Van Buskirk. Cyriak's animation "MOO" has featured on the front page of Wired. His 2009 video "poo pants" features an animated sample of broadcaster Alan Titchmarsh singing a repeated refrain from the bowls of a series of toilets, some of which fly through space.
As a freelance animator he has been commissioned by Coke for a Coke Zero advert, the video sharing website Sumo TV, and a music video for Grand Popo Football Club, among others.

On 14 August 2014 he released a video entitled "malfunction", of which Cyriak himself said: "I've no idea what this video is. It crawled out from some dark corner of my computer after evolving from the virtual maggots that feast on rotting film footage.
