Since google and youtube searches often yield quite a lot of garbage or poor quality results, i thought it would be a good thing to resurrect the link list, and to collect some "gems".
I guess everybody loves gems ;-)
It would be nice to add some information about those links. Please add only links that are true gems! No one likes fake gems ;-).
