Insta.ants consist in artsy artificial ants that paint unique antworks from input images. Instagram images tagged with #instaants are collected and supplied to the painting ants that exhibit the resulting antworks on their Instagram profile as well as on a repository where you can also find videos of their painting processes.

How to use insta.ants.


In short, to have the insta.ants painting for you, post an image on Instagram using the hashtag #instaants in the caption. Insta.ants will discover this post, paint an antwork, and post it back to Instagram with a tag to you. Instagramers with private profiles, before using our tag, must follow the insta.ants so they can follow you back and see your #instaants posts.


How it works


There are three cores that work together: finder, render, and uploader. First, the finder periodically visits Instagram and collects the most recent images tagged with #instaants. Second, the render paints each collected image with an ant species selected at random. Finally, the uploader periodically uploads the resulting antworks to Instagram.


The render core is based on our previous work Photogrowth. Inspired on ant colony approaches, the render produces emerging paintings by simulating the behaviour of artificial ants while they travel on a canvas. The trails of the ants are represented by continuous lines, working like paintbrushes. The intertwinement of all trails, together with their variation in width, direction, and colour, produce expressive renderings from input images that would be hard to execute or even imagine.

We have defined a set of different ant species. Each has its own behaviour, sensory capabilities, life span, reproduction rate, free will, etc. This way, different ant species produce different types of imagery. To test and select a set of ant species, we use an evolutionary algorithm to evolve their characteristics. The figure above shows the same input image painted by different ant species. In the future, we will allow users to choose the ant species that will paint their images, possibly by using an hashtag to identify the desired ant species.

The rendering algorithm is able to output vector images, allowing the production of large-format artworks. You can find high resolution versions of all antworks as well as a video of each painting process at this repository. To find a specific antwork, use its ID, e.g. antwork_abc, or the name of the author of the original image. Both the ID and the author of an antwork are presented in its caption on Instagram. In addition, we can provide higher resolution and vector versions of any antwork upon request.
