Mobile World Congress was the launch point for products such as the great Samsung Galaxy S6 and the new Huawei Watch.

Flagship devices, however, were not the only devices to be released at the show. Here are five of the weirdest gadgets unveiled at MWC 2015.

1. Xiaomi Yi Action Cam With "Cat Harness Accessory"

Xiaomi's new Yi Action Cam was not all that surprising of a release, but what is interesting is the "cat harness accessory" option that comes with the device.

This essentially allows users to strap their new action cam to their kitty and take the best YouTube cat videos ever made. The purpose of this? Well, that's left up to the imagination, but one can only imagine what kind of mischief a cat might get into with a camera strapped to its back.

2. Runcible Smartphone

The Runcible is essentially the "anti-smartphone." It is not a traditional smartphone, but it does have smartphone capabilities. It's not a wearable device, but it could be considered a "smart pocket watch."

The idea of the device is that it's the most non-intrusive smartphone available, allowing users to focus on the task at hand. However, it must be connected to speakers or a headset to take a call, largely defeating the purpose of a smartphone.

3. AVG Invisibility Glasses

Worried that you'll be auto-tagged in photos on Facebook that you might not want to be tagged in? You need AVG's new invisibility glasses, which essentially emit ultraviolet light. This light is not detectable by the human eye, but it certainly is detectable by a camera, making it seem like the wearer has light all over their face.

The glasses will not be available to the general public for a while. AVG said that the glasses were more of an experiment for using the technology.

4. Pizza Hut Click'N'Pizza

Sometimes picking up the phone and calling to order pizza can be a little too much work.

That's why Italian startup La Comanda created a magnetic button that lives on the fridge, allowing users to essentially push a button to order pizza. It's that easy. Press the button, and a pizza will be sent to the user's house. Pizza Hut locations around the country are said to begin selling these buttons this summer.

5. VR Hot Air Balloon Ride

Hot air balloon rides are expensive and can be scary for those who are scared of heights. Who needs the real thing when there are virtual reality hot air balloon rides?

The simulation was showed off by SKC Telecom, which combined the use of virtual reality headsets, rather expensive headphones and even a rumbling floor.
