SPACED OUT

Thursday, August 19th, 2021

Tim has made a new trailer for the Enigame 2021_2 puzzle hunt this fall – the spaced out edition.

A hitchhikers guide through the Berlin traffic galaxy

Monday, December 10th, 2018

For those who are interested in what keeps us busy – here is one thing: Local politics and in particular Berlin traffic planning.
If you are able to endure german subscripts you might watch our attempt to convince people that their ideas of traffic load removal may have the opposite effect of what they think.
If not -Tim had only very few hours to work on the music but you might just enjoy his lofty kind of ambient electronica.

ShutterSploshShredderPlots

Sunday, October 7th, 2018

Remark: The code as posted at the randform post ShutterSploshScatterPlots needs to include the new Content Security Policy.
That is you have to embed the following lines (at least thats how it worked here for the moment) into your html head:

<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<meta http-equiv="X-Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<meta http-equiv="X-WebKit-CSP" content="default-src 'self'; script-src 'self'">

Moreover the javascript has to be pasted into a separate file and referenced accordingly within your html body, like for example as:

 <script src="shutter.js" type="text/javascript"></script>

In case you feel a bit overcharged by all that – as a courtesy for you I quickly filmed the program output with my mobile and turned it into a gifanimation, which you can watch after the ” Read the rest of this entry”.

galaxy flush reloaded

Wednesday, November 29th, 2017




pan and zoom as usual

In 2006 Tim played around with swarm simulations in processing and ended up with funny flush like settings. We tweaked the parameters in such a way that it ended up looking like and sounding like a galaxy being flushed down the drain and made it into the art work “dipper galaxy flush” where dipper refers to the wellknown patterns in the constellation Ursa Major. Our comment wasn’t though referring to a particular galaxy there but to galaxies in general – which could include our own.

If you look at the processing code you see that Tim’s simulation doesn’t use e.g. Newtonian gravity, although Tim used a force which is similarily “centralizing” as dark matter.

Inspired by discussions about dark matter and dark energy and general relativity at John Baez’ social media I wanted to get a feeling of how important the feature of dark matter is in order to allow for galaxy formation.
The above is a realtime javascript simulation using purely newtonian gravity with no dark matter but two giant masses (indicated by blue circles, which size is not proportional to the smaller circles) and something that could be called an “inelastic binding”. That is if the distance between masses is smaller than some number then those “close-by” masses behave as if they stuck together as in an inelastic collision, or in other words: the velocity of a mass is set to be the weighted average velocity of the close-by masses (details in the code, how much inelastic collision you want is set by the parameter “mix”).

It was acutally not so easy to find a configuration which somewhat mimicks galaxies, but the above looks a bit as if, I find. If I find the time I may add a 3D viewer. Try yourself – the source code is open.
Here how a scientifically advanced galaxy simulation, which includes dark matter looks on a super computer: World’s first realistic simulation of the formation of the Milky Way and here an interview with the author Lucio Mayer. Just like us many other users think it looks like a filmed flush – if you read the comments.
Here another simulation by Fabio Governato on his youtube channel: The Formation of a Milky Way like Galaxy. He has a whole variety of galaxy formation videos.

remark: the simulation is a modification of Mike Bostocks canvas swarm simulation at https://bl.ocks.org/mbostock/2647922

update 1.12.2017: There was a mistake in the addition of the z-speed, which is now corrected in the above version. Luckily the correction did affect the overall appearance only slightly.

ShutterSploshScatterPlots

Friday, September 29th, 2017

Mohammad Ali (mohdali) had made a nice illustration of the socalled rolling shutter effect. He wrote a programm in javascript which uses the library d3 called Rolling shutter.

This program was used by artist Scriptique to program a kind of “paint-by-number recreational occupation for your browser” (as the artist called it). It should display something like “a paint drop dropping”.

The program has a MIT licence and you can see how well your browser paints by numbers by pasting the program into a file and then opening the file in your browser (tested with firefox).

Sunday Drone

Wednesday, June 7th, 2017

Tim has to cope with an increasing workload, moreover heavy commuting also takes its toll, so he currently doesn’t get too much recreational time – even not on weekends. But over pentecost he now managed to create a nice drone with matching visuals.

Gesture Steered Turing Machines

A new astlab project, which comes closer to realize something which I have carried around in my head for now almost ten years.

Generation Z: Renoise

Sunday, February 16th, 2014

IMG_0644.JPG

For Berliners and those who can afford to go to Berlin for a quick trip I would like to mention an absolute must see exhibition, namely the exhibition Generation Z: Renoise about the russian musical avantgarde in the 20s and later which is curated by L. Pchelkina, A. Smirnov, P. Aidu, K. Dudakov-Kashuro and E. Vorobyeva. The exhibition is unfortunately not as highly promoted as it should – given how fabulous it is! I hope that this post makes some more people visit it. It is definitely worth it! The exhibition is in the Künstlerhaus Bethanien, Kunstraum (unfortunately not so easy to find), it runs until Feb.23, 2014. It is free of entrance and open from 12:00-19:00 o clock.

The exhibition has the themes: Projectionism and Radio-ear, Revasavr, GIMN Institute, Theremin, Graphical Sound, Industrial Noise Machines, Amateur Noise Instruments and Destruction of Utopia. Below is a small excerpt from the respective themes. A lot of details can also be found in Andrei Smirnov’s book “Sound in Z“.

critter under the couch

Wednesday, March 6th, 2013

A sort of brief follow-up to the last two posts about simulations. Here a link to Tim’s simulation of a critter under the couch.

Tim likes to learn more about 3D modelling – last but not least – for the purpose of enhancing his mathematical galley. steampunkmoth has been Tim’s newest Blender-baby.
