Wow that’s really cool to see people interested in using head tracking and eye tracking together! Before I saw this forum I created my own version that is focused specifically on mouse emulation. It can use a variety of head trackers including EyeX 4C, TrackIR, and SmartNav. The mouse follows where you look around the screen. It doesn’t have the teleport feature on a mouse press but I like how you do it Nate! Check it out at http://precisiongazemouse.com/
Also, I would like to try Clippy but I’d rather not install Java because it constantly needs to be updated. I’ll add an issue to your Github project to make a version that doesn’t require a JRE.
