These light-up jellyfish from Swim Ways have LEDs inside and glow as they float across the surface of your swimming pool with their legs dangling beneath the water. I suppose you could also put them in your bathtub or whirlpool if you so desire. Keep in mind that they’re not going to throw off a huge amount of light, but they still look cool. They sell for about $43 (USD) each over at Amazon.

While distance swimmer Diana Nyad probably wouldn’t want these light-up jellyfish in her lap pool, I rather like the way they look. And it’s certainly way better than having actual jellies in your pool, right?

These remind me a bit of those ADEL inflatable earbuds that are (literally) bloated up with air to provide a softer cushion to your ears while you plug those babies in. Maybe because they appeared translucent and slightly jelly-like, too.

The Elecom otokurage earbuds are a delight to look at, and hopefully, they will be equally delightful to use, too. They come in six different colors that are extremely appealing, from basic black and white, to the more bright colors like pink, purple, blue, and green.

The earbuds don’t just come in the usual boxes or cases either; in fact, they’re housed in plastic water bottles (without the water, of course) that just adds to the whole appeal of these darn things. They will most likely be sold only to the Japanese market though, but you might be able to get your hands on them if you’re resourceful enough (*cough* eBay or Rinkya *cough*).

The curvaceous lamp is loaded up with bright RGB LEDs that can change to any of 16 million unique colors and brightness levels through the use of a unique touch-panel interface. It actually works sort of like the color palette control you might find in photo-editing and painting software. Check out how it works in the video below:

In addition to fixed-colors, you can set the Jellyfish to a color flow mode with a variable fade speed between the colors of your choice. And you can switch off the front side illumination, leaving only the Jellyfish’s clear “tentacle” structure which provides a cool backlighting.

When powered off, the Jellyfish maintains a stealthy look, with a sleek black top and white bottom.

While I haven’t found any U.S. retailers for the Yantouch yet, the have numerous Taiwanese and Japanese retailers as well as an French retailer listed up on their website. Pricing in Japan is set at ¥14,800 (appx. $160 USD).
