Fibonacci Clock with Bluetooth Sync: Math-Themed Desk Clock Unique STEM Gift for Adults, Engineers & Teachers Modern Office Decor Educational Timepiece

Once you get the formula, its lots of fun.

Anyone that steps foot into my work area immediately asks what is the thing with the colorful blocks? As soon as I tell them it's a clock I can see their mind going into overdrive and confusion trying to quickly figure out how this tells time. So far nobody has figured it out or known what it is exactly. Telling time on it can be challenging but only because the clock cycles through different colors and that's a huge downfall because as soon as I almost have it all added up it ends up changing colors. This takes some time to get used to and to be able to tell time on it efficiently but nonetheless it's still amazing and fun shelf piece to have. The colors are blurred at the edges and it would have been nice to see this with more crisp defined edges where each color meets the other. But it doesn't effect the speed at which you can tell the time. Not a piece for everyone but if you like gadgets or to impress people then this would be a great item. I'd recommend it to the crowd of people that it would fit for.

Was fun while it lasted. Just when the return period was over it stopped working. The USB C charging port is bad and the battery won’t charge.

This is actually a very cool device. In the end it is just a clock, but a whole new way of reading it. It uses colors in a Fibonacci sequence, instead of a normal boring display with numbers on it.This is a very cool clock, and it is possible to read lol. I lost hope for a while, and was very confused. Finally I get it, and I hope you enjoy figuring it out as well. Looks great, and is very unique. Great gift idea, highly recommended.

I must admit that I am very often confused when trying to read this FIBONAX Fibonacci Clock with Bluetooth Sync. But the challenge is part of the charm! This clock is definitely a conversation starter. A very cool gift for the smarty pants in the family etc. I am still getting the hang of this, but it's pretty cool just as an LED display. The colors do bleed at times, but not always. The brightness is pretty good and it has a great battery life.4/5

I'm a sucker for oddly designed/unique/gimmicky clocks, so this was right up my alley. This clock is far more engaging than expected, blending unique design with precise timekeeping. While it makes a bold visual statement, it’s also highly functional.The display consists of squares arranged according to the Fibonacci sequence, with multiple possible ways to represent each hour. Users can select from four different display modes, choosing the one that best suits their aesthetic preference. The colors within each section indicate different variables in the time calculation, while the size of each section represents its numerical value.Brightness can be adjusted across four levels, and there’s a convenient button to announce the time aloud. The clock is intuitive to read after a little practice, making it feel like an interactive puzzle. A backup battery preserves settings during power interruptions, though it primarily runs on USB power. One standout feature is its automatic Bluetooth syncing, which ensures accuracy by briefly connecting to a nearby phone. Manual adjustments can also be made using buttons on top.The shifting colors draw plenty of attention, but the true appeal lies in the clever approach to timekeeping. It’s a great conversation piece and a rewarding addition to any workspace, especially for those who enjoy logic-based challenges or innovative design.

The colors bleed in to each other and cause blurry squares.UPDATE: The seller reached out and stated they know it's blurry. Which is pretty shady considering they have pictures that look otherwise. The seller told me they basically know that's how the clock is and it's blurry and in the future they will maybe make it better. They offered no resolution. No refund. No replacement. Just basically a thank you for buying their garbage.

Show your friends you are on the top of the smart list. Really cool clock, well made and has a cool style.
