Cymatics Experiment

after researching how to create such effects, i decided to give it ago. there is a frequency generator in fl studio so i decided to use that, unfortunately the only speaker i had was a small portable speaker which when placed under a tray only vibrated the particles randomly at certain frequencies. if i was to do this again i would invest in a larger speaker or one that i could take apart, and also do it in an environment where no one would mind the loud single note tones.
