Portrait of the Mona Lisa is more than 500 years, but it is still a favourite target for the experiments of artists and developers.
That’s what caught me just recently:

From the moment I first saw the Lebedev’s Verbarius clock I wanted it to show several strange things.

So, a few weeks ago I realised my plan:

reverse engineering Verbarius clock

You could just watch the short proof movie or check the detailed project description on my recently redesigned site. (Yeah! at last I did it :)

The other day, when, due some reason, I had to excavate some very old archives, I’ve found some pictures that I drew 20-odd years ago in the unforgettable editor Art Studio on my speccy.

Armed with a strange set of utilities I dug some .bmps (from .scl (from .trd)), and it turned out that the images with a stretch of the imagination can be attributed to the pixel-art and can be useful, as I have my hands itched to play with the de-pixelation algorithms for a long time.

The most interesting article I found in this area was the relatively recent article “Depixelizing Pixel Art” by two guys from, afaik, Microsoft. However, they didn’t provide any ready-to-use code, so I had to look into several related projects. From what I’ve tried, more or less meaningful results came from potrace and vectormagic:

Today I am sharing a couple of links for xkcd-styled charts drawing:

Consider these depending on your language/platform of choice:

Happy drawing!

How do you think a one-dimensional Wolfram’s automata will look like, if we map it into Peano (Hilbert) curve?

Have no idea? Me too. So I decided to check it out:

I could have done this in a hour or so using python, but I had never sought for easy ways, so I tried to make the online interactive visualization.

It took a dozen of nights and a lot of nerve, considering the fact I didn’t mess with clientside development for ten years, and looks like it became even much more chaotic since then. But now I know some kung fu.

A year ago, Stephan Rafler from Germany published a paper about the continuous generalization of Conway’s Game of Life:

Actually, it’s more of an approach rather than a strict set of rules; so, there is enough space for experiments. Among other types of such systems’ behaviour, gliders, tubes and some kind of carousels were discovered. A lot of videos of various simulations can be found at the author’s youtube-channel, and the emulation software itself is available there (including the sources).

Pat Ashforth and Steve Plummer, the couple from UK, run a nice site, WoollyThoughts, dedicated to the “mathematical knitting”:

Among other things, there are some knitted optical illusions, flexagons, math puzzles and fractals.

Sarah-Marie Belcastro, US, runs a similar site, The Home of Mathematical Knitting, with a more serious mathematical bias — she has some knitted projective planes, hyperbolic surfaces and even the hat in the form of Klein bottle. Also, she provides an extensive collection of links to other sites and resources on this topic.

And Jana from Germany knits different patterns based on Escher’s works:

Frank Haase — the designer from Germany — has created the interesting sculpture, “Trinity”: it’s a cube made of the plexiglass with a cloud of balls inside. These balls appear as 3 different QR-codes while being watched from different directions:

Two american artists Daniel E. Kelm and Tauba Auerbach have made the RGB color-cube as a book:

Sebastian Schmieg (the media experimentalist from Germany) investigated an interesting idea last year: he ran a recurrent google search by image, starting from the empty transparent PNG:

Video recording of the entire process is available on vimeo. A few more variants (based on different seed-images) can be found on the project page.
Also, Sebastian has collected a nice set of broken kindle screens.
