Dreamr app: a relaxing experience?

A dreamachine is a strobing flicker device, invented by Brion Gysin and Ian Summerville, that pulses light in a frequency range relating to alpha waves present in the brain while relaxing. Originally created using a turntable, a bulb, and a cylinder, you close your eyes and and the pulsing of the lights as seen behind your eyelids is supposed to cause varying states of relaxation, sometimes creating colorful patterns of swirling lights.
Pulses from 1-4 beats per second are supposed to cause deep relaxation, while pulses from 8-13 beats per second are said to cause a waking sleep often with accompanied by psychedelic shapes and trippy colors.
Author William S. Burroughs, one of the first proponents of the dreamachine, wrote:
"Subjects report dazzling lights of unearthly brilliance and color. ...Elaborate geometric constructions of incredible intricacy build up from multidimensional mosaic into living fireballs like the mandalas of Eastern mysticism or resolve momentarily into apparently individual images and powerfully dramatic scenes like brightly colored dreams."
The Dreamr app tells you to turn the brightness all the way up, choose a number of beats per second and a color, and then to hold the device's screen up to your closed eyes and see what happens. The buttons to choose beats per second were quite small and hard to consistently tap.
I gave Dreamr two ten minute tests, both in a comfortable recliner with my iPhone resting on my eyes. At 13 beats per second I found nothing at all, outside of noting that the speed of the flickering seeming to slow down and speed up after about 6 minutes. At 4 beats per second I may have been a bit more relaxed after about 8 minutes but that could have been due the quality of my recliner. Overall, I wasn't affected. Your results, however, may vary.
The app comes with a warning that this should not be used by small children, photosensitive people, or those that react badly to flashing lights. The price is $US.99.
We'd be very curious to know of the experiences of anyone who has used Dreamr, or in fact, any dreamachine. And that, my friends, is what the comments section is for.

Dreamr [iTunes Link] is an app for the iPhone or iPod touch running OS 3.1 or better that turns your device into a dreamachine. And what...

I've used a real DREAM MACHINE many many times and if ur a person with any type of open mind and with an artistic bone in ur body, IT WORKS!!! For god sake William S. Burroughs enjoyed it! and no cancer or pseudoscienc.

"DO YOU EVER want to change the way you see the world? Wouldn't it be fun to hallucinate on your lunch break? Although we typically associate such phenomena with powerful drugs like LSD or mescaline, it's easy to fling open the doors of perception without them: All it takes is a basic understanding of how the mind works.
The first thing to know is that the mind isn't a mirror, or even a passive observer of reality. Much of what we think of as being out there actually comes from in here, and is a byproduct of how the brain processes sensation. In recent years scientists have come up with a number of simple tricks that expose the artifice of our senses, so that we end up perceiving what we know isn't real - tweaking the cortex to produce something uncannily like hallucinations. Perhaps we hear the voice of someone who is no longer alive, or feel as if our nose is suddenly 3 feet long."
Ok, found more or less what I was looking for.
" The studies from Fytche have shown that the stroboscope is a friendly and reliable tool for the induction of visual images by altering neuronal activity in and between the thalamocortical circuits [15]. A change in thalamocortical activity has also been associated with a variety of neuropsychiatric disorders ('thalamocortical dysrythmias'), including the Charles Bonnet syndrome (CBS) [24]. The CBS consists of complex visual hallucinations that typically occur when there is an inadequate stimulus to the visual system. Patients generally suffer from eye conditions like macular degeneration and are aware that the phenomena are not real. Especially in the dark they experience a range of hallucinations that are very similar to the ones induced by the stroboscope [25]. As a result, the stroboscopic hallucinations can be used to study the underlying mechanisms of the CBS and possible therapeutic interventions, like medication. "

Very good TED Talk about Charles Bonnet syndrom:

The hallucinations engendered by flickering lights are really typical, and this is a great way to learn what hallucinations are without taking any drugs. This is really true and tested stuff, no pseudo science there.
As for the claims of brain entrainment, relaxation, etc, I don't know.
I used to use a light/sound device. I was in my early twenties, and working a grave shift. When I got home around 9am, all my housemates were just getting up, so I'd talk with them, then I'd be quite awake because it was bright morning daylight, so I'd play around, wander the city, come back and think of going to sleep but then my housemates would be returning from school and I'd stay up talking, then eat dinner with them, and then finally I'd realize it was after 9pm and I would need to get on my bike (to travel 12 miles) in about two hours. I'd rush upstairs, set my light/sound 'dream' device to ramp me down to the deepest state (theta?) and ramp me back up in an hour and a half.
I'd fall asleep after about 10 minutes or so, and come back awake when it was almost finished ramping me back awake (beta waves) and then I'd rush out on my bike.
I did this five days a week for a few weeks. Not that it is recommended (I eventually fell asleep and started dreaming while at work standing in the kitchen preparing food) ... but it definitely gave me some deep zzzs.
I can't imagine just flashing lights would do the trick though. I'd think you'd also need the sounds to really help entrain your brain.
Maybe the app could second as a Rave accessory. :D
The free flashlight app "myLite" has had strobing effects that I used for the same thing.
Please try my "Journeys" app for both relaxation and more fun sounds too.
My favorite computer app for binaural beats is BWGEN but it is a Windows-only program - haven't found anything I like as much for the Mac.
I'll stick with my bottle of wine.

At 17Hz I get patterned hallucinations. Pretty cool. This has been used to study the formation of hallucinations in conjunction with brain imagery.
Lost my bookmarks, so can't point you to it.
