Scientific Revamp of Insomniac's Spyro [revampedspyro.blogspot.com]
I love this to pieces. It's a shame the blogger (Anya McNaughton) never finished it but I'm grateful that it's still online.
It seems the blogger carried on with the project on deviantart, but later deactivated her account. I tried her dA (tasteslikeanya) in the Wayback Machine, but it hadn't preserved any of the Spyro project pieces. However, I did find one of the improved maps shared to Tumblr from when Anya's dA page was still active.
A site that's been online since the early 2000s!
