Hi Geminauts, I would add another bunch of words about this... I really watch with admiration anytime someone is pushing the boundaries of the protocol to its limits, I think is smart and useful, I don't feel upset or annoying, on the contrary I think it has the beneficial effect to understand better what we can achieve or what we can not with Gemini. This effort of creativity is totally different to propose changes to the protocols thus I really encourage all the people with such expertise to continue to experiment with Gemini wherever your creativity leads you! A big thank you to each and everyone of you!!!
