generative art: flowers

It started with this tweet about someone called Ayliean apparently drawing a plant based upon set rules and rolling a dice.

And because generative art in itself is fascinating I am frequently pulled into such things. Like this dungeon generator or these city maps or generated audio or face generators or buildings and patterns

On the topic of flowers there’s another actual implementation of the above mentioned concept available:

Posters – Visions of the Future

If you like artful posters just as much as I do you might want to take a look at this great treasure of high-quality print-ready posters from NASAs Jet Propulsion Laboratory:

Imagination is our window into the future. At NASA/JPL we strive to be bold in advancing the edge of possibility so that someday, with the help of new generations of innovators and explorers, these visions of the future can become a reality. As you look through these images of imaginative travel destinations, remember that you can be an architect of the future. 

Hertzian Landscapes

I played with SDR – Software Defined Radio – back in 2013. I’ve still got the equipment around.

Now that I am thinking about it – there is a practical use-case that I will look into in the coming months for sure for it. And just to mention this use case here: With SDR I could create a more versatile 443/886 Mhz receiver.

Anyhow. SDR hardware allows you to access a whole spectrum of radiosignals at once. And a common way to visualize the spectrum is to draw the amplitudes in a line add each new measurement as a new line – color/brightness coded.

What you get is some sort of waterfall diagram that looks like this:

Hertzian Landscapes (2019) is a live visualization of the radio spectrum. Unlike visible light, waves in the radio spectrum cannot be perceived by us directly yet this space is teeming with human activity. Hertzian Landscapes employs a digital receiver to scan large swaths of radio spectrum in near real-time and visualizes thousands of signals into a panoramic electromagnetic landscape. Users can zoom in to specific frequencies by positioning themselves in front of the panorama as if controlling a radio tuner with their body, giving them a sense of walking through the spectrum.
From radio broadcasts to weather satellites and from medical implants to aeronautical navigation, the radio spectrum is divided into hundreds of designated slices each tied to a specific application. Based on a localized frequency database that describes these slices, signals are annotated to provide information about their theoretical type and application.

Experimental Audio Tool: SuperCollider

SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It is free and open source software available for Windows, macOS, and Linux.

SuperCollider features three major components:

scsynth, a real-time audio server, forms the core of the platform. It features 400+ unit generators (“UGens”) for analysis, synthesis, and processing.

sclang, an interpreted programming language. It is focused on sound, but not limited to any specific domain. sclang controls scsynth via Open Sound Control.

scide is an editor for sclang with an integrated help system.

hyper-realistic japanese train

There are some things that, when looked at closely, just amaze you. This picture was like that for me:

I stumbled on this picture on Twitter. At first it looks like your average japanese train. With the blue seat cushions. The adverts and hand rails. All normal, right?

If you read the text or start to zoom in you will find that this is not a picture taken with a camera. This is a drawing.

This visual art is called Hyperrealism and it takes a lot of dedication and skill when done free-hand.

The artist had posted this picture on his Twitter feed. He explains that he had drawn it whilst commuting on the train over the course of a month. He used an iPad Pro and MediBang Paint. Of course he also names the train-type: Tobu Series 5050 used by the Tobu line in the greater Tokyo area.
