“A color for the weather” @space_nietzsche

I wanted to get experience using nodeJS so I decided to do my bot using it. After looking at many bots out there and following a couple of tutorials on how to make a bot, i decided to create my own!

Every 30 min., Space Nietzsche Bot  selects a city and grabs its current weather information. Once I have this information I use the temperature, precipitation and wind bearing to calculate a color representation. I create an image with that color and then i post a new tweet.

Originally the tweet had a static “The current color weather of city <bla> is <img>”

I realized this was very boring so I added some adjective randomness to make the tweet more interesting! Now it is : “The <adjective and connector> color of city is <adjective and connector>.

When adding the randomness I also added a random var that will sometimes add a random hastag to the tweet.

Final Project Research

Cubepix Demo Test – by Xavi’s Lab

I am interested in doing something with projection mapping and mixing hardware like Arduino. I really liked this project because is a very good combination of both hardware use and projection mapping. I dont like the fact that the installation is supper loud. I know it is thanks to the motors, but If I end up using both projection mapping and Arduinos, I would try to minimize the amount of motors it had to keep the volume as low as possible. Apart from that i really like the effect the boxes do when they are rotating! It looks very cool. I also liked how they added the kinect as an interactive input. I would definitely add one too. I really think that some experiences like this the kinect adds a very special touch.


This project is more focused on kinect and projection mapping. As mentioned earlier, I feel when it comes to tracking, the kinect makes it easier to create interesting things with the depth camera. I really like all the effects the dances create. It looks like they are the ones disturbing the environment and i really like how that looks. I also liked the minimal color pallet used. I felt like the high contrast makes a stronger connection between he dancers and the disruption they are creating in the background and the mapping. I have seen many similar effects to this one, so I would definitely try to innovate the canvas, maybe by adding a real static object that will add to the canvas or combine it with LED or some type of sensor that would alter the canvas, making it less flat

Creative Canvas – OF & ofxAddons

Creative Canvas


I have always liked image manipulation but had never had the chance to really experiment with it. I took this assignment as a chance to see what I could create by extracting information from any image. After looking at the openFrameworks addons, I decided to use ofxUI, ofxCV, ofxTriangleMesh, and ofxColorQuantizer.

I used ofxUI to give control to the user (me) to be able to manipulate the image. ofxCV is the one giving me all the main information of the image, mostly the contours. ofxColorQuantizer and ofxTriangleMesh are both being used to add the effects to the image.

So Creative Canvas breaks an image into the main color pallet and finds the contours thanks to this colors. You can switch between contours by clicking ‘c’ to see what it selects.

In the UI, there are 5 main features that can be applied to the image: “draw triangle”, “draw mesh”, “draw outline”, “draw particles” and “random”. What these features do is decide how you are going to draw over the current contour. If you select random, it will randomly select one of this effects.

You can loop as long as you want through the image and very cool effects come out (most of the time).



Many iterations where applied on the color selection and on how the mesh and particles should look and move. Also the colors. Initially I was thinking on using a particular color pallet for all the virtual objects (triangles, particles etc) but it looked soo busy that i decided to keep the same pallet as the image.

Voro Snake – Parametric Object

Voro Snake

I was looking at some very cool stuff done with voroni cells and decided to give them a try.
I wanted my object to be as closed to the user as possible, so i decided to allow the user to create it by drawing a shape with the mouse. After the shape was draws, a voroni cell pattern will simulate the shape the user did.

To be able to manipulate it, I added three main constraints: width, height and number of subdivisions. The interface has an UI that allows the user to easily change this parameters to construct their shape.


You can rest it at any point and re draw another line or keep changing the parameters of the objects. I called it Voro Snake because I realized that most of the shapes end up looking like a very abstract snake 🙂
