My name is Íñigo Quílez (don't worry, you can write 'Inigo Quilez', that's fine). I was born and grew up in San Sebastián (a.k.a. Donostia), a beautiful city in the Basque Country, somewhere in Europe (Spain). I love life, I admire the universe in a pretty natural sense, and I enjoy skiing, mathematics, writing, dance, computer graphics, nature and other things I probably can't say. Also, I have a resume.

Seventeen years ago I started this site as some sort of boxroom where I could drop my fractals, demos and other creations. Soon I started adding explanations, tutorials and presentations too; even code and other random stuff like personal pictures and a blog. Then at some point I decided it was time to split the big mess into smaller messes and point to them from a common kind of index. Guess what, that index is exactly where you are right now.

this is where you have to go to look for finalized works like demos, videos and images. Most of them are motivated by the demoscene, meaning that they are programs you must download and run in your pc (like if it was a video game). You will also find video recordings of the pieces here when appropiate. All the material here is made by myself and my collaborators.
this is the place where I host articles, tutorials, explanations, code, and presentations related to maths, images, fractals, demoscene and computer graphics. If you are a fractal freak, a computer science nerd, or a math geek, or simply a demoscener, searching for some info, this is what you are looking for.
here I'm sharing the libraries and frameworks that I use for my C++ and JS demos, experiments, prototypes and products. I do update these very often, so use at your own risk.
this is the interactive part of this website where you can find a couple of computer graphics applications that you can experiment with. Hopefully this will grow bigger over time.
when I don't have time for writing an article, i do some live coding instead, and put it here. Seeing a live coding session might not be the best way to learn, but it might be fun to you seeing some live hacking of formulanimations or mathimages?
el trastero is not a blog on boring computer graphics news, but there are few computer made images. It's not a blog about my ideology, although I sketch (and intentionally only sketch) few deep thoughts. It's definitely not a blog where you should learn maths, but you will find some formulas and constructions. It's not a blog about the latest news, but you will find some important secrets about the world. It's a blog of mine, but you will for sure not get to know me by reading it.

Everything in this site, both content and structure are dynamic and change very often, so you are welcome to check it out from time to time. Also, if you want to tell me anything (about a bug, a question, a suggestion, whatever) just write to me at
