Ink drawings of fragmented blue horizontal lines arranged in irregular blocks of textured paper, with a red seal in the bottom right corner.

Close-up detail of the blue line blocks and the red stamp bearing geographic coordinates and scale.

Twelve drawings from the series laid out in a grid on a tatami mat, each showing a unique variation of the blue line pattern.

designed for #ptpx 2025 : exploration with elevation data, scales, and lines. horizontal lines that break where the ground is lower, arranged in a grid. The seal indicates scale and geographical coordinates. #dataviz #penplotter

I do wonder if the recipients got the postcards I sent out. Well I’m sure one did :)

As an addendum to my #ptpx post just now: It's always fun (genuinely!) to go through my stamp "collection" and piece together combinations that work for whatever price increases Deutsche Post has applied since I last bought stamps (while still physically fitting on the cards)!

Every December, there's a pen plotter postcard exchange called #ptpx (I've participated for the past three years: https://mastodon.social/@doersino/109460427108652884 & https://mastodon.social/@doersino/111688094152383358 & […]

Pen plotting the #ptpx postcards!

Posted my #ptpx (penplotter postcard exchange) postcards today. 7 to USA, 4 to Germany, 1 to Sweden, 1 to Portugal. Hope they are received well.

A bit late, but finally got my #ptpx cards out in the mail. This year has a dithered view of Vancouver and a couple outputs from a generative piece I did.

A #Genuary design becomes a Xmas card. These cards are now on the way to participants of #ptpx25! Thank you @paulbutler.org for organising it! Happy New Year!

Potato printing plot party postcards A postcard designed for the 2025 plotter postcard exchange #ptpx based on 'Potato Printing,' a game that M.C. Escher played with his kids.

I wrote about the postcard I designed for the 2025 plotter postcard exchange #ptpx on my blog, based on a potato-based game that M.C. Escher used to play with his kids.

Incidentally, #ptpx postcards have been mailed out. I like this idea of exchanging physical art from digital plans. Tangibility is valuable.
