Experimental software which does not sometimes work properly (no positive effect to EEG).
Software can change measurable brainwaves a bit but how it affects to brain performance is unknown.
Sometimes with certain "should-work" settings you get "lack of focus" effect that disappears after one night of good sleep.
Requires fast CPU and running times even for small effects are long (hours). Typically, you need about 100-1000 iterations before some useful results. If you calculate an iteration in 30 seconds, it means 0.8-8 hours of stimulation.
Not for people with epilepsy. Flashing lights and sounds.
Command-line software is hard to use (there will be graphical user interface version of the software later).
