Illusio is a live looping tool that enables musicians to sketch their own loop controls in a multitouch table. Illusio has received the support of Rumos Itaú Cultural Arte Cibernética 2009, and was shortlisted in the Interaction Design Association (IxDA) Interaction Awards 2013.
The Illusio was prototyped in Processing and Openframeworks, in 2011. More information can be found on my old website.
