EEG brainwave visualisations shown as various shape forms and colours
This is what my attention and meditation brainwaves look like visualised on a LED matrix - red LED = my attention and green LED = my meditation data. The visuals grow or contract as the levels of each signal go up and down. I've used Mindwave Mobile, Bluetooth and Arduino, with C code to make this prototype.
