Can You See the Parallel Stripes in This Optical Illusion?

Magical entertainer and illusionist Victoria Skye makes the impossible seem possible for a living. There aren’t any smoke and mirrors involved in her latest trick: Her “cafe wall” optical illusion is the result of some clever design.

In the image above, the darker blue horizontal stripes appear to lay at zig-zagging angles across the frame. In reality, they’re perfectly parallel to one another. The slanted effect is created by the use of alternating patterns (in the top row, the interior pattern is drawn to lean slightly to the left while the one beneath it leans slightly to the right, and so on).

The alternating colors also contribute to the illusion. As The Telegraph points out, the illusion was inspired by a tiled wall that can be found in Bristol, England. The staggered nature of the white squares against the green makes it seem as if the parallel rows were built at different angles. Though the Bristol wall is the original, there are plenty of examples of cafe walls around the world if you’re looking for more illusions to make your head spin.

Still Struggling to Solve a Rubik’s Cube? There’s an App for That

Solving a Rubik's Cube is an easy way to impress your friends, but you don't need to be a math genius to crack the algorithm. With help from this app spotted by Lifehacker, you don't even need to memorize any tricks.

The Magic Cube Solver is a free app for iOS that calculates the fastest route to solving a Rubik's Cube based on its current pattern. To use it, start by inputting your cube's information by tapping the squares in the app's model and selecting the right colors. Hit "solve" and the tool will display step-by-step visual instructions you can follow to complete the puzzle. The stages are all laid out together and each one comes with a picture of what the cube looks like before and after you make your move, making it easy to follow along. No matter what configuration you're starting with, Magic Cube Solver will show you how to solve it in no more than 22 steps.

The app acts as more than a cheat to a particularly hard pattern. If you're interested in boosting your Rubik's Cube skills, you can select the "solve and learn" option after entering your information. This not only shows you the steps to take to solve it, but why it suggests those steps in the first place. Rather than applying a one-size-fits-all trick to every cube configuration, which isn't always efficient, Magic Cube Solver will teach how to recognize different patterns and show you which tricks work best for each one. The ultimate goal is to equip you with the skills you need to solve any Rubik's Cube without the app's help.

Magic Cube Solve is available to download from the App Store for free. The free version only shows you how to solve the classic three-by-three square cube. Solutions for two-by-two, four-by-four, and void cubes cost extra. To learn more about the Rubik's Cube and its origins, check out our list.

Washington State Department of Transportation Tweets Images of Possible Sasquatch Sighting

Washington has long been a hotspot for sasquatch sightings, and the latest possible glimpse of Bigfoot comes straight from the state's government. As K5 News reports, webcams run by the Washington State Department of Transportation captured a figure that bears a strong resemblance to the hairy cryptid.

Most footage shot by the traffic cam above State Route 20 on Sherman Pass is standard fare, but recently, it spotted something unusual. The WSDOT Twitter account shared stills from the stream on January 22 with the caption: "Have you noticed something strange on our Sherman Pass/SR 20 webcam before? If you look closely by the tree on the left there looks to be something ... might be Sasquatch ... We will leave that up to you!"

The images show a dark figure skulking by the trees above the highway. Skeptics not convinced of Bigfoot's presence in Washington State received another piece of evidence the next day. On January 23, the official WSDOT Twitter account for Snoqualmie Pass tweeted video of a possible sasquatch striding across the wildlife crossing on I-90. It's not clear whether the images show something inhuman, a person pulling a hoax, or someone just bundled up for the cold.

Bigfoot sightings are so common in Washington that the legendary creature is written into the state's law. In 1969, Skamania County, Washington, passed official legislation stating that killing Bigfoot was punishable by up to five years in prison.
