HOUDINI Magazine presents: The Decker Applications & Ultilities Jam! Or, the Decker App Jam for short. 

It's no secret that we LOVE everything about Internet Janitor's Decker here at HOUDINI Magazine, from Mindape's incredible library of cold crack classics, to Salty Slug's gems like Panopticon, and of course the experiments like //cheat.deck// San Andreas, we've constantly been pushing what can be done with this small but powerful desktop tool.

Tool? Yeah! Decker is an application in and of itself! You can use it to make flash cards, keep notes, or as a sketchbook. But what if you took it further? Wiggly Paint, Tabletop RPG character sheet generation, clocks, calculators and more galore! 

This game jam celebrates the other side of Decker. From experimental interactive clickables to office-suite-worthy software, Decker can do a whole lot. The jam is a call to build ultilies and applications using Decker as a base. We look forward to seeing what people build, and will be featuring our favorite submissions in HOUDINI magazine!


There are many tools and applications already made in Decker, so if you're looking for inspo, it can be found in droves, here are some examples:
