Just updated the current version of XNADominos, which now incldues source code.

Major changes include:
Changed from BasicEffect to shaders (first attempt using shaders so no idea if I’ve used them correctly BUT it works :))
Flyby Manager window overhaul – now hopefully more resilient and working.
Flyby manager not shown on startup http://www.eta-i.org/ambien.html (new menu options)
Can load & save flybys (and simple flyby included)
Can toggle display of flyby points
Standard domino to bridge up domino now works correctly
Couple of other minor bug fixes.

Docs still to come (honest)
