7 Secret Passageways & Hidden Doors

1. Wardrobe Hidden Playroom

Like something straight our of Narnia, this wardrobe is actually a secret entrance to a playroom. The owner of the house had the wardrobe and figured he might as well add a touch of magic to the house for a pretty amazing result.

2. Home Theater Ticket Booth Hidden Door

Do you like  unique hidden doors and cool home theaters? Well this one is orderable from Creative Building Resources. CBR's elaborate hidden door features a programmable, scrolling LED sign built into the top of the frame, while the interior of the hidden door functions like your traditional ticket booth. For those who intend to staff the ticket booth, or at least fill it with a costume-draped dummy, the interior is accessed through a full sized cabinet door at the back.

3. Victorian Façade Hidden Garage

Not sure about your neighborhood, but mine has strict codes about what you can and cannot do to the facade under our historic preservation laws. Same in San Fran. By hiding the space behind a retractable facade indistinguishable from the rest of the historic Victorian apartment house, theses owners were able to avoid running afoul of the city planning department strict appearance codes.
Here's how it works:

4. Bookcase Hidden Door

The bookcase, holding rows of books, a stuffed dachshund and a volleyball, silently swings outward, revealing a tiny, well-lit study room.

5. Painted Wall Hidden Door

This one speaks for itself, I'd say.

6. Staircase Hidden Door

7. Mat Hidden Wine Cellar

Ever wanted a wine cellar but didn't have the space to build one? Here's a secret solution! The cellars are kept at ideal temperatures, insulated on the sides and top. Cool air is piped in and warm air is piped out. Even when no air flow is needed for temperature purposes it is kept moving to keep the air fresh. People have had these installed in all kinds of ways, from flush- and hidden-door versions to entrances that intentionally boast their presence.

New AI-Driven Music System Analyzes Tracks for Perfect Playlists

Whether you're planning a bachelorette party or recovering from a breakup, a well-curated playlist makes all the difference. If you don't have time to pick the perfect songs manually, services that use the AI-driven system Sonic Style may be able to figure out exactly what you have in mind based on your request.

According to Fast Company, Sonic Style is the new music-categorizing service from the media and entertainment data provider Gracenote. There are plenty of music algorithms out there already, but Sonic Style works a little differently. Rather than listing the entire discography of a certain artist under a single genre, the AI analyzes individual tracks. It considers factors like the artist's typical genre and the era the song was recorded in, as well as qualities it can only learn through listening, like tempo and mood. Based on nearly 450 descriptors, it creates a super-accurate "style profile" of the track that makes it easier for listeners to find it when searching for the perfect song to fit an occasion.

Playlists that use data from Sonic Style feel like they were made by a person with a deep knowledge of music rather than a machine. That's thanks to the system's advanced neural network. It also recognizes artists that don't fit neatly into one genre, or that have evolved into a completely different music style over their careers. Any service—including music-streaming platforms and voice-activated assistants—that uses Gracenote's data will be able to take advantage of the new technology.

With AI at your disposal, all you have to do as the listener is decide on a style of music. Here are some ideas to get you started if you want a playlist for productivity.
