It's an adding and visualization tool. You can create items that have scores, put them in boxes that add the scores up, and then rearrange and resize them in 2D space. Changes are synced in real-time across browsers, so someone can watch your changes if you're working on a public board. [more inside]
The famous Tiled map editor is a powerful open source application for creating tile-based maps for use in video games, but what happens when we bring that level of versatility to anything that can run a modern browser? Add in the ability to create maps as large as you can imagine, allow editors in the same space to see each others work in real time, and this open source project could help facilitate a level of collaboration previously difficult to achieve. The end goals of this include use as a classroom teaching tool to spark young imaginations and hopefully generate interest in software development through simple games. It's a work in progress, so please feel free to let me know if there's anything you'd like to see.
The first of a serious of neat little side projects from my usual work on MapBox and the like - a new kind of map (I call it a 'squiggle') and a new pretty map. But, hopefully a lot more than that - I documented the process of creating the map in serious detail, and it goes over re-teaching myself high school trig, writing a scraper for Garmin Connect, trying to fake being a real artist, and figuring out some new map interactions. There's more to come, and ideally this convinces the big groups that hold onto our data to let us get at it to make more beautiful things.
Finally out in the open - a project I've been working on at work. Sweet, beautiful open source map design.
