Nick Sayers took 630 individual wooden coffee stirrers and combined them into this awesome geometric sculpture, titled Hyperbolic Coffee Cactus. By carefully bending them into a repeated shape, then attaching them to one another with 1260 toothpicks, poked through holes drilled into the stirrers, he created this insanely complex sculpture. Here, you can see a little bit of how he pulled off this monumental feat in the detail image below:

I’m pretty awestruck at the amount of patience and precision this must have taken to pull off such a perfectly symmetrical looking work of art. I think I’ll stick to stirring my coffee and picking my teeth, and leave the sculpture to the professionals.

The Time Cube carves off one corner of its 6-sided box to form a series of layered triangles which rotate to tell the current time. The largest triangle displays hours, while the medium-sized one tells minutes, and the small spinning triangle on top acts as a second hand.

At first glance, I thought it might be confusing to read, but if you just think about the triangles like the hands on a regular clock, it’s not too difficult to get the hang of it.

The Time Cube clock is available now from gadget importer Chinavasion for about $12 USD.

These Irregular IQ Cube puzzles might just blow your head off. Somehow, you’ll need to figure out how to get all of these oddly-shaped, color-coded pieces to form a proper cube.

A set of two puzzles is just $7.90, so pick up a couple and let me know how long it takes for you to solve one. Hint: The solution does not include throwing the puzzle against the wall and watching it shatter into a bunch of pieces.
