While working in the garage, I spilled some sheetrock (wall board / gypsum) from drilling a hole. The modules were vertical and it just got on the peaks of the hills. Looked freakin' awesome, such a light dusting of early snow. So I ventured out to recreate it. I used Sheetrock (R) also know as gypsum. Sawed from the middle, sieved and then shaken over diluted white glue. It has to be really fine powder. The finest screen I could find was a tea bag strainer. You might also use talcum or other white, non-medicated (smell) powders. Spray the area with whett water (water it a drop of dish soap). Spray diluted white glue (2 or 3:1 water:glue) so it is sorta wet. Shake well sieved power over the area. lighter coating looks cool from a typical view distance. Up macro close, it looks like hail (ice snow) as I only used simle sieved gypsum. A heavier coating gets whiter but you still see the larger hail sized white 'spots' at the borders. Just use known fine powder or a finer siecve than I used. .
