Music

I like the subject of tuning music instruments, because it is an unsolvable sudoku with many social and emotional consequences to it. I'll add a story about a keyboard soon.
To get tuning freedom, I've been making two guitars and a bass fretless. I made several music tools that I need to document here, and I've been sensors for more expression.

And I like to play harmonica while walking. I recorded that through someones camera that I could pickup a signal from.

Related to music, are the speaker setups that I do, to project sound in a room in a veristile way.

Dark Trails

Distilling how I see the flight of the animals living in close proximity to us has led me on quite a quest. I call the result dark trails, as they are the opposite of light trails. There are many apps to make light trails, but none to make dark trails, so I put a lot of effort into this.

First Phase: Making dark trails of bats and jackdaws

Second Phase: Making stereo trails, in parallel view and anaglyph

The Forest at Night

Hoping to get across how soothing the forest is for me at night. Shooting in infrared helps a lot to block the city lights, and only shoot the natural light.

RGB Color and Infrared with moonlight, or even stereo infrared in moonlight.

Stereo phone pics at night.

Obviously, I also shoot infrared in sunlight. A lot, actually. Also in stereo. I removed the IR blocking filter from several cameras. It is through using those, that I accidentally discovered that the moon reflects so much IR.

Portraits

The bigger the camera, the less it matters, and the more people are willing to sit still for it a while. I'd like to shoot more, and bigger direct color positives.

Clocks

Vasilis, my friend who built this site, inspirered me to make two clocks so far.
