ReWild: Replacement for Wildfire
Background
Wildfire was a freely-distributable educationally-focused disease spread simulator developed by Neptunesys for the 16-bit Windows platform (archived website). While a mirrored copy is still available from here, potentially useful if you have a 16-bit or 32-bit (that is, not 64-bit) Windows system to run it on, it seems no longer to be developed or maintained, and support for 16-bit apps is ever declining as 64-bit is effectively the standard nowadays.
This niche is filled by ReWild; I’ve pulled it from Tumblr now but it is still included below. I originally wrote it to supply to my biology teachers at the time, who wished to still use the demonstration. After some reluctance, I have finally opted to fold it into the repertoire of things I’m signing off with the HarJIT moniker. It is written in JavaScript as a DHTML applet, and hence should work on any system with a decent browser (although no guarantees). HTML5 support is not required, but is used when available.
