We know, returning to work after an all-too-short long weekend leaves you just wanting more time off, but rather than skimming through those pictures you snapped and refusing to get back in the groove, why not force your brain to meditate and release those negative vibes? In an admittedly bizarre how-to guide , the folks over at MAKE have detailed Mitch Altman's Brain Machine, which reportedly enables you to slip into deep thought, sleep, or peaceful nirvana by syncing up your brain waves with pulsing lights and sounds. Odd as it may sound, the homegrown trip inducer purportedly utilizes an SLM (Sound and Light Machine) to "phase in new brain states by switching frequencies back and forth." Of course, we're still a bit hesitant to put our retinas at risk in order to legally experience hallucinations , but be sure to hit the read link for the step-by-step guide, and tap the via if you're interested in catching a video before subjecting yourself.
