(CNN) — A long list of companies once again showed off an assortment of cutting-edge technology and oddball gadgets at the Consumer Electronics Show in Las Vegas last week.

There were new twists on foldable devices, cars that changed colors and smart ovens that live-streamed dinners. There was a self-driving stroller, a pillow that pulsates to reduce anxiety and a locker from LG that claims to deodorize smelly sneakers in less than 40 minutes. At the event, some people gathered in groups, sitting in silence, to test out the latest virtual reality products.

While some of these devices may never find their way into households, the products on display offer a glimpse at some of the biggest tech trends companies are anticipating this year and in the years ahead.

Here’s a look at some of the buzziest products announced last week:

BMW iVision Dee concept car
BMW unveiled a wild color-changing concept car with 260 e-panels that can change up to 32 colors. During a demo, different parts of the car, including the wheel covers, flashed in varying hues and swirls of colors. The technology, which relies on panels that receive electrical impulses, isn’t ready for production. (Breaks between panels and what looked like wiring could be seen on the outside of the car.) But just imagine being able to drive a sporty red car on the weekends and then a conservative gray model when you go to work.

Bespoke AI Oven
If you think snapping photos of your meal for Instagram is overdone, now you can livestream your dinner as it cooks in real time and post it to your social feeds. Samsung’s new AI Wall oven features an internal camera that can capture footage of your baking food or allow you to keep tabs on it without ever leaving the couch. The oven, which uses an algorithm to recognize dishes and suggest cooking times and temperatures, also pushes notifications to your phone to prevent you from burning meals. The oven will launch in North America later this year; a price has not yet been announced.

A $3,300 self-driving stroller
Canadian-based baby gear startup Gluxkind was showed off its Ella AI Powered Smart Stroller. It offers much of the same tech seen in autonomous cars and delivery robots, including a dual-motor system for uphill walks and automatic downhill brake assist. It’s meant to serve as an “extra pairs of eyes and an extra set of hands,” according to the company’s website — not a replacement for a caregiver. The Ella stroller is able to drive itself for hands-free strolling — but only when a child is not inside.

Shiftall Mutalk mouthpiece
No gadget at CES this year was as striking as the Mutalk mouthpiece from startup Shiftall. The device, which looks like a muzzle, features a soundproof Bluetooth microphone that makes it difficult for others in the room to hear your voice when you’re on calls. The company thinks the $200 gadget will come in handy for everything from voice chats and playing online games to shouting in VR when you don’t want to disturb anyone else nearby. Instead of hearing you, they will simply see your new mouthpiece; you can decide which is worse.

AtmosGear electric skates
If you ever wanted to hit 15 miles per hour on roller skates, this electric pair from French startup AtmosGear promises to help get you there. With a battery pack that holds an hour charge and the ability to travel over 12 miles, the skates can clip onto any existing roller skates, turning them into motor-propelled footwear. The skates are currently available for pre-order for $525.

JBLTour Pro 2 earbuds
You’ve probably heard of smartphones that come with headphones, but what about headphones that come with a screen? The JBL Tour Pro 2 earbuds adds a touchscreen to the case to bring smartwatch-like capabilities by allowing users to control its settings, answer calls, set alarms, manage music and check battery life. No launch date has been announced, but the new buds will cost $250 when they eventually go on sale.

A new look for foldable phones
Some companies offered a new twist on the foldable phone concept. For example, Samsung Display’s Flex Hybrid prototype features a foldable and slidable display (the right side slides to offer more screen space). Meanwhile, the Asus $3500 Zenbook 17 Fold OLED — the world’s first foldable 17-inch laptop — picked up significant buzz on the show floor, acting almost like a large tablet that can be folded in half when on the go.

Dubbed “the world’s first awareable,” the $500 Nowatch is a watch… with no clock. The Amsterdam-based startup of the same name launched the device to help users monitor stress, body temperature, heart rate, movement and sleep. But unlike other smartwatches, there’s no watchface — instead, a gemstone sits where the touchscreen display typically goes. “We’ve replaced the traditional watch face with ancient stones, celebrating the belief that time is NOW,” the company said on its website.

Honda and Sony’s Afeela car
Honda and Sony have joined forces to create tech-filled electric cars that, they say, will be both fun to drive and filled with the latest entertainment innovation. According to the CEO of Sony Honda Mobility, its cars will recognize your moods and be highly communicative and sensitive to your needs. The car will have screens on the outside so it can “express itself” and share information and will be able to “detect and understand people and society by utilizing sensing and [artificial intelligence] technologies,” according to the company. That’s why the company named its first joint car brand Afeela, in that it just has to “feel” right. But it’s unclear if we’re afeeling that name.

While it typically requires a blood panel and a visit to the doctor’s office to learn more about vitamin deficiencies, Withins says its new $500 U-Scan device can tell you similar information right from the comfort of your own toilet. The device attaches to existing toilets and collects data from your urine stream to detect vitamin deficiencies, check hydration and monitor metabolism, according to the company. An additional device called the U-Scan Cycle Sync tracks periods and ovulation cycles.

Schlage Encode Plus Smart WiFi Deadbolt
Schlage’s new smart lock is one of the first to work with Apple’s Home Key functionality, which allows users to upload their keys to their Apple Wallet and unlock their deadbolted front door directly from their phone or Apple Watch. The lock also works with Amazon Alexa and Google Assistant for voice controlled, hands-free locking. Available in two finishes, the deadbolt can manage access codes, view lock history and handle multiple locks at once. The lock, which will cost $300, will be available for purchase late this spring, according to a company press release.
