Nice! I did something like this back in one of the apartments I lived in during college. Use any specific program for the picture and/or special paper or did you buy it like this?
Used adobe acrobat to print the image so that each tile is exactly the same size. Normal paper as glossy photo paper reflects too much light. Laser printer to print the image, and I used pink rigid foam insulation board from home depot. the most time costuming part is the cutting the foam to sizeWhat material is that? Looks good
