A long time ago we wanted a program to generate grids for use for projection line up.
A company we used to use a lot had one but would not sell it to us to use, and so i made my own.
Originally it just generated grids for a single screen, then i was asked to make it handle blended screens, and then to have the ability to generate a lineup grid for times when you had to throw away pixels.
The latest version adds the ability to generate bars and greyscale.
GridZ is available for both the mac and the pc and soon for the Android.
The current version of GridZ is V2.4.2
Please E-mail me for download link and let me know if you want it for the Mac and PC
