An app the filters the light in your screen to make it show nothing legible from your screen. You have to wear glasses that add a frequency or some missing piece of the visual spectrum to make the image visible again. Great for office and cell phone screens when you want privacy. 

1) A sunblock blaster on your door. As you walk out, it blasts your whole body with a mist of sunblock. It identifies the individual and blasts spf based on their preselected settings. 

2) Mist cooling zones under patio umbrellas. A very fine mist released to cool the area under umbrellas on very hot days. 

3) Waterproof projectors – to hide in a pool and project the silhouette of a shark swimming in the pool. 

4) Roomba for lawnmowing. 

5) A pool that notifies you if a child is in the water. Does so by measuring water displacement, calibrated to the weight range of children (20-90 lbs or so). 

Like Uber, the girl requests an expert makeup artist. Within minutes she’s paired with an expert via cell phone or Web cam for a personal consultations and tutorial. 

1) A cell phone break box. A box that locks for one hour a day, so that you can lock away your cell phone and live life disconnected.

2) A personal safety pod. A lightweight, indestructible box that people in war torn or hazardous environments can use for temporary shelter. Can be used in hurricane or tornado zones, in schools and businesses for active shooter safety, etc.

3) A window into another universe. A box with a headset attached that let’s you look into a random feed of a random camera set somewhere in the world. 

4) Instead of carrying (and misplacing) a cell phone, you have a floating cube following you. Pluck it out of the air when you need information, or talk to it like Siri or Alexa. 

5) The minimalist box challenge. Pick a medium or large box, and pack it with essentials to live out of for 30 days. Use only items packed in that box to survive for 30 days. 

1) A foldable, wallet sized umbrella.

2) An e-ink kindle the size of your cell phone. For reading on the go, without killing battery life or your eyesight.

3) A folding cell phone. Super thin. So small you can keep it in your wallet. Unfold it once, and it’s a standard sized 5 inch cell phone. Unfold it again, and it’s a tablet.

4) (stolen from Josh) A pocket sized 3d printer.

5) A pocket sized air conditioner. I don’t just mean a fan circulating air. A full blown air cooler.

… This category was a lot harder than I thought…

1) Who needs a door? Why not have a electric or plasma barrier that won’t let outsiders in, but recognizes your biometrics to let you pass.
2) A button that extends a little hand from the doorframe, for those times when my hands are full of groceries, and I don’t want to put the bags down on the dirty floor. Hang them on this retractable hook instead.
3) A doorbell that captures the fingerprint of anyone that rings it. Typically, burglars will ring the doorbell before breaking in. This would capture their fingerprint.
4) Automated doorman. A door that recognizes if I’m receiving a delivery, opens a hatch on the side to take it, and signs for the parcel. It takes a picture of the delivery person in the event of shenanigans. Can also receive take out in case I can’t come to the door.
5) A smart door that will remind you before work to take your keys, or an umbrella, or whatever else it detects that you may need or forgot.

1) A killswitch button on your nightstand. Press it and it turns off all bedroom lights, TV, silences your phone, lowers the shades, and says good night.
2) Robot mom. A robot that tucks you in and gives you a kiss on the check good night.
3) A robot dog that lives on your bed. It feels and cuddles like a dog, without the need to take care of it.
4) A bed tent. I’ve noticed that I sleep best in the woods. You put a tent attachment on your bed, and outside of it a sound machine makes the sounds of a crackling fire, and the woods at night. The machine also give a light ember glow to add to the fire effect.
5) A little self powered robot that you put on your back, and it rolls around acting as a massage therapist.

1) Beet the Meat – a restaurant known for its quality steak and veggies.
2) Curl Up & Dye – a hair salon
3) Alfred’s Closet – a uniform store for the help
4) Kettle & Bell – high end men’s fashion line. The Lululemon for me. Stores are built to look like old school gyms.
5) Cyborg Reviews – a blog reviewing all new wearable tech. From smart glasses, to wearable health devices like Quell.

1) A decibel measuring app that tracks how much noise you’re exposed to. Like a fitness tracker, but a sanity tracker. Once you hit a threshold of unacceptable daily noise exposure, it notifies you, as a reminder to escape somewhere quiet.
2) An interactive map of city quiet zones. Using the noise tracker above, it maps the quietest and noisier areas in your city.
3) Nap Pods. I said it before, I’ll say it again, heavy business districts need nap pod stations, set up similar to massage parlor rooms. They could be operated 24 hours, doubling as a hotel overnight.
4) Sell noise canceling headphones to corporations so that they can lend/rent to employees.
5) Create an interactive game where people can hunt for secret zen monasteries. They’re always on the move in the city. And only the first person to find the hidden key gets exclusive access to them for a week. Each is beautifully decorated and stylishly minimalist. The hunt for zen!
