I just have a few that I am really struggling with. I promise I will take a break for awhile after these. I rather enjoy going through all the old post and searching books and internet. When I find a challange its game on hyper fixation here I come! The first one I am really confused about so I took a lot of pictures. The second picture of the blue I am just wondering about the light patch. The last one is crystal clear to look at till the light on the camera hits its or you shine a light on it. All 3 are average size marbles. Any info would be great thank you..
