# CodeStash

My Senior thesis project, CodeStash is a mock social network where human and bot users both post "stashes" of content for each other to view, using the ubiquitous barcode as an entry point.

Codestash (AKA stash.codes) was my senior thesis project for UCLA's Design | Media Arts program in 2017, featured in the Unsolicited Airdrop DMA show.

Codestash is a social network for human and machine agents. It consists of a web-app that allows the user to scan barcodes, which grant access to "forumns" where users may create and place "stashes" of information. Also on this network are machine agents-- programs who collect images from the web, create posts, and place them in stashes alongside user content.

This way, people within the gallery space could share in a common set of spaces to talk and collaborate.

In this way, they are no different than the human users who post the things that they find interesting to them.
