This LED clock from British designers Jimmy Loizeau and James Auger. Part flycatcher, part timepiece, the gizmo harvests insects on a sticky roller covered in flypaper, before dropping the corpses into a microbial fuel cell.
The dead bug is then digested by the bacteria within, and the chemical changes are used by the cell to power the clock. Simple, huh? 
The insects become trapped on the flypaper stretched over its roller mechanism. 
At the base of the roller, a scraper removes any captured insects.
They fall into the microbial fuel cell beneath, where bacteria digest the fly and cause chemical changes that the cell can extract power from.
The energy is used to power the LCD clock and keep the roller revolving.

One of the fine artists over at ETSY brings us a cluster buckler for our brain. Behold the math clock. Finally a use for all those equations you’ve gathered over the years. Well this clock dedicated to any of you who think that " i'm smart enough" or just like math and feel curious about this clock can check up the answer on explanation below......the rest, just think that its your nightmares....

It is actually the first time I've seen this clock like this, it might be rare but wonder if it is expensive. However, I enjoy the different and sometimes bizarre designs but when it comes to telling time that’s where the problems start.
So this is a time cube but instead of hands it has triangles. The large one is the hour hand the middle one - minutes and the smallest one is for minutes. I think and this is only a guess, that you can tell time by looking at the numbers near the black line. What I like about this clock is that it transform into different shapes for 12 hours. That means, every one hour passes, the cube starts to move.

Just guess what time is it ?
