I wasn't happy with 8 different themes on my website, so there's now a 9th one, which lets you customise the main settings. It's driven by about a dozen #CSS custom properties (I love theming in CSS holy heck…I should write about it). It was a good… distraction, to build this.
Anyway, maybe you want some "Matrix" or bubble gum style instead of my painstakingly and lovingly crafted themes? That's fine, express yourself everywhere! Even on my personal website!
