For an out that website this one Shirley, by surprise. I was online along time ago when I came across this for the first time. I thought wow this is pretty cool. Of course I bookmarked it never came back. Then a few years later I see this app in the store, and I think this is the same one? Long behold, it's that same site back again as an app. I was ecstatic. I downloaded it, and to my surprise it still worked. I saw that there are more options if I pay for it, so I thought "what the heck, let's give it a shot." Surprising me again, this app delivered a plethora of different illusions that did not leave me bored. Plus, they take thirty seconds to take effect, and wear off in thirty seconds to a full minute. I would definitely recommend giving this app a chance.
