He has also produced the majority of the content for The Shiznit, a free pocket-sized comic funded by adverts and released in various cities around Ireland.
Other works include Robots Don't Cry (a children's illustrated book), a one-shot Freakshow special written by Rob Curley, and a series of silent strips in 2000AD under the banner "Bob Byrne's Twisted Tales".
His works include the original graphic novel Mr. Amperduke, a story told entirely in pictures without words, which Byrne published himself (trading as Clamnut Comix) in 2008.
This led to Byrne being commissioned to produce original stories for the Megazine's parent publication 2000 AD, using the same text-free storytelling technique.
Byrne is also the creator of Dr Moku learning system, used in teaching Japanese Hiragana and Katakana mnemonics.
