I made a macOS screensaver that draws the warming stripes one year at a time. It holds all 1,069 locations from showyourstripes.info and nine ways to build each picture. Free download. Stripes by Ed Hawkins @edhawkins.org karaman.is/blog/2026/10... #ShowYourStripes #dataviz #macOS
 A MacBook on a table outdoors, with autumn trees behind it. The screen fills with the warming stripes for Sweden, 1850–2025: thin vertical bars in blues and pale shades, turning to deep reds toward the right. A small label in the corner reads "Sweden 1850–2025"

A crema-coloured spiral chart. Each coloured bean is a country, placed at the minutes a barista works to afford a small cappuccino: Australia at 10 minutes near the top of the outer rim, most of Europe and North America within the first half hour, and Pakistan at 4 hours 37 minutes near the centre. Bean colour shows region and bean size the number of cafés surveyed.
