Many of my playschool sites use a flat-text content management system called GetSimple. I like deploying it on simpler sites — three-to-six-pagers — as it lets users edit their own pages without running the risk of breaking the templates and layouts (though if you know what you are doing, it’s also pretty easy to soup up a basic GetSimple site into something quite stylish).
I was into tardigrades before they were cool.
Having briefly been a student of invertebrate zoology in 1973-74,
the background image on this website shows a colourized (and much enlarged) view of Hypsibius dujardini, a tardigrade.
