volume material changing - 3d led screen - edgar - 03-09-2020

hi. i want to do some effect but there is no any solutions on the web. 
1) i have cube with 100 x 100 verticies grid. its my hidden animated(wave ripple etc) control geometry — «volume1».
2) on this grid i have tyflow particles spread only on verticies(cube’s) and constraint to them(object bind — lock to surface) 
3) i have hidden sphere (animated moving and animated deformations) moves through particles — «volume2»

I want my tyflow particles change material in this moving sphere volume2. Basic cube volume1 — transperant glass, in moving volume2 — vray light. 
It will be some kind of 3d led screen.
