This isn't a blog, but more than 20 years ago I saw a Flash web game which I've always remembered as the most beautiful piece of interactive online content I'd ever seen.
It took a while to find it again... (I searched Google images until I found a screenshot that looked right.) Somebody archived it and resurrected it with Ruffle. (It looks better if you go to "Full Screen" mode.) But the aesthetic was just incredible...
I give you -- "A Murder of Scarecrows."
