Interesting question. You might consider https://commons.wikimedia.org/wiki/File:ADC_Icon.svg as a starting point. It draws a useful contrast between the analog and digital domains. It's recognizable to regular people, I think. It's not computer-y, but your web page possibly supplies sufficient context? Perhaps you could use a strike-through on the digital side to emphasize "that's not the one". -----Original Message----- From: vcf-midatlantic [mailto:vcf-midatlantic-bounces@lists.vcfed.org] On Behalf Of Evan Koblentz via vcf-midatlantic Sent: Saturday, September 15, 2018 3:10 AM To: vcf-midatlantic Cc: Evan Koblentz Subject: [vcf-midatlantic] Ideas for "analog" icon? There is an under-construction page on my Lego robotics website about analog computing. I need a simple image to represent the idea of analog. Any suggestions? I'm not looking for a picture of hardware, I'm looking for something more like an icon even if I have to make it myself... but an icon of what? It needs to be something recognizable to regular people.
