A short while ago I was invited to participate in µChip3, an arts event curated by Antonio Roberts & Sam Wray which involved chiptune, digital art, hacking, modified hardware and much more. My role was to perform live visuals to accompany performances by some notable chiptune artists, so I set about building a custom browser-based visualiser based on the piece I produced for the BYOB 2013 exhibition.
Visualiser applications need to work across two windows (a control window with which you create and modify visuals, which appear in a display window), so working out how to produce an application able to function reliably in this way was my first concern. I worried it would involve some fiddly work with a local server, but after some research the solution proved straightforward: simply store commands in local storage via the command window, which are then be detected by the display window using the storage event listener.
As well as multi-window web applications, local storage can also be used to keep web apps open in multiple tabs in sync with each other, or even to stream the output of a HTML5 canvas from one window to another. Read on for some demos…
