From 6f6e52dd63c3adb522da9ff5ed270d40b085f8d2 Mon Sep 17 00:00:00 2001 From: Marc Mintel Date: Sun, 4 Oct 2026 14:58:35 +0200 Subject: [PATCH] feat: section on web presentations, in German and English A presentation built as a website instead of a slide file: why, for what, and when slides are enough. The main drawing shows the same presentation as a slide and as a web page on a projector, a laptop and a phone; the slide keeps its format and shrinks, the page rearranges. Four small drawings stand next to the reasons. No prices: none are agreed for this yet.
