I completely forgot I uploaded VistaPro 3.20 (the scenery renderer) to the Internet Archive, where you can run it from your browser. For those sudden urges of wanting to create some landscapes.

Includes the MakePath tool.
Don't forget to take screenshots of your creations! Nothing can be retrieved from the disk the in-browser DOSBox keeps, as far as I know.
(Please be patient with the Archive's speed, they're dealing with persistent DDoS attacks at the moment)
