a pen with an uncomfortable similarity to the one on whiteboard.fox

granted this can be entirely inaccurate because i dont use the site, but based on my keen observational skills, this seems to be similar. ....ish.
* i made this with my personal stabilization/pressure settings, and while the brush has no pressure settings, adjust the stabilization for that web browser type correction (maybe 20 notches higher than your usual settings?)
additionally, if you want to use it in a similar fashion to the original program, draw with this pen on a vector layer utilizing the vector eraser.

this setting works like wbf's weird trash eraser.
anyway enjoy and subcocnsiously thank my girlfriend for bringing it up 4 Billion Years Ago.
