Location Based Mixed Reality WiFi Glitch Art
I've been really busy lately. Earlier this month, a hackerspace in Warsaw Poland published a guide to hacking an awesome device called the Zsun, a WiFi card reader that's been hacked to run OpenWrt. It costs $11 and has 64MB RAM, 16MB SPI Flash, and USB SD Card Reader and is perfect for converting into an AVALON node. http://imgur.com/a/XP6oX
The vision I have for this art project is that the zsun listen to ambient WiFi signals around it and extract image data to retexture itself. We will need a script to process the images. We will use imagemagick for creating the textures for the leaves.
Basic stuff covered in https://hackaday.io/project/4423-stereo-vision-experiments
# Convert input image into a binary black and white stencil convert leaf.png matte:- | convert - stencil.png # Make black transparent (can also add fuzz) convert -transparent Black stencil.png mask.png
# Composite the mask over the background image

Creating a patch of land, the area could symbolize the signal range.
Mapping the textures onto a Japanese Maple 3D model.

This is already looking better than the basic Multiplayer VR sample in Project Tango store:
No offense to Johnny Lee, he is awesome and I've always been a great fan of his work! Lets build the Metaverse together :)
Web Scraping and Virtual Reality is a powerful combination to visualize data and use computers to create art. A good primer and my personal recommendation for those wishing to get into scraping is Web Scraping with Python. Not only is it a lot of fun, you'll obtain a deeper understanding of the internet and build up some very useful skills along the way.
# Pythonpy will evaluate any python expression from the command line. Install via: sudo pip install pythonpy # Make sure you also have BeautifulSoup installed sudo pip install beautifulsoup4 # scrape from imgur and then name images via sequence curl http://imgur.com/ | py 'map(lambda _: _.attrs["src"].partition("//")[-1], bs4.BeautifulSoup(sys.stdin).findAll("img"))' | xargs -n1 wget >/dev/null 2>&1 && ls | cat -n | while read n f; do mv "$f" "$n.jpg"; doneThe next step is to incorporate these images into our DOM.
To be continued..
