Freestanding sign post design

via LumberJocks.com RSS Feed - All Posts http://lumberjocks.com/topics/47743

I’ve been asked to build a freestanding sign post and signs for a school fair. There will be multiple signs (maybe 5 or so) on a 4×4 post pointing the way to the various games and activities. The sign will be inside the school so no worries about wind blowing over the sign but lots of people and kids milling around.

Any recommendations on a good design? that is likely not to tip over easily or create a tipping hazard?

My first thought was something like a big coat rack with legs:

But found two other photos on the web that might work.

Any other ideas??

Bead and String Puzzle

I found a picture of this puzzle a while ago and decided to make a load of them for Christmas presents. The aim of the puzzle is to move the beads so they are on the same loop. So far nobody has managed to solve it (except me with a set of answers).

Floating Blocks Optical Illusion

via Mighty Optical Illusions http://www.moillusions.com/2013/03/floating-blocks-optical-illusion-2.html

Our favourite professor has done it again! Akiyoshi has created showcased illusory pattern titled “Chidori” (which is some kind of a bird if I understood it correctly), which gives an impression that the inner block is moving in upper-diagonal direction. To amplify the effect, simply scroll the page up and down slightly. After a while, you’ll see the inner block floating on top of its background. If you’re lucky, you’ll experience the 3D stereoscopic effect without having to go cross-eyed or wearing those clumsy 3D glasses!
