I like doing crystal ball photos and bring it everywhere but forget to use it most times! I never tried a glass ball tho, it looks clearer. Does the picture appear upside down like a crystal ball? I generally have my partner in crime @silvergingerman hold it for me. Almost the best way to do it, it's hard by yourself trying to focus, photograph and hold! I'm sure there is a passer by that might be willing to help with your projects.

I like the effects you added on the second pic. Nice shots!
