Summary
You cannot easily tell what version of Raspberry Pi you have just by glancing at it. I have more than a few of these laying around and some are 2GB, some are 4 and some are 8. No more wondering which one is which. Sometimes we make beautiful artistic things with our laser, but they very much can be a useful tool as well.
