There's a new Virtual Table Top game aid for GURPS using the
FoundryVTT engine:
GURPS 4th Edition Game Aid (Unofficial), or GGA.
GGA has been reviewed and approved by SJGames and is available now for anyone wanting to use FoundryVTT as their virtual tabletop.
Although the version number is 0.9.3 (as of this writing) it is functionally complete.
There are a number of
videos demoing the workings of GGA, as well as a written
guide/manual (Google Doc).
You can get more information or request additional features at the main author's
GitHub account page or join us on the GURPS Discord (channel vtt-foundry). (I am one of the contributors.)
There's a thread on the forums about GGA -- if you have any testimonials or questions for the author/contributors, refer to that thread:
