yes I have seen those sand/salt vibrating with the harmonic frequencies videos too - the geometry is stunning! It's pretty comforting to know change is inevitable, we are all constantly moving through action and reaction - I fought the changes for a long time - like trying to tread water.. not realizing that if you just give in and relax you'll float with the waves.
Thanks for reading @bashadow - glad you liked the post too! I'm having a lot of fun playing along :)
