This cardboard panorama of the Acropolis folds and slots together, to create a picture that you can hang on your wall. But this is more than a picture - as you move, the buildings seem to swivel, and follow you. This is a really impressive optical illusion, that can be quickly and easily constructed. The cardboard is prefolded and slots together without needing any glue.Free plastic poster hangers are included with every print. The finished image is 66cm wide and 27cm high.Related products:

Pentakis is a three-sided mirror kaleidoscope, made from a simple but ingeniously formed sheet of metal that creates an astonishing optical microcosm!In order to generate the maximum light reflection, the aluminium surface of the Pentakis is vacuum coated with silicide and titanium. Incident light creates a twelve rayed Kepler star. Thanks to the five fold symmetry axis, the three dihedral angles (60, 60 and 72 degrees) reflect and re-reflect light to create a spherical pentakis dodecahedron, generating a total of 60 reflections! Pentakis is therefore a 60-fold kaleidoscope. Pentakis is 15cm in length, and comes with a cardboard stand. Alternatively you can hang it from a fine thread.Pentakis is designed by a Swiss inventor, Professor Caspar Schwabe, from the Kurashiki University of Science and Art.People who bought this item also bought:

A remarkable new material has recently become available that has an enormous number of potential applications. It is called QTC (Quantum Tunnelling Composite), and has won many major awards for innovation. Its name may sound complex, but what it does is essentially quite easy to understand - when you squeeze it, its electrical resistance drops. In fact it changes from an almost perfect electrical insulator to near metallic conduction levels when a force is applied to it. Thus, the change in the resistance of QTC when it is compressed means that it can be used as a switch. If a pill of QTC is connected in a circuit, together with a battery and an electric motor, then the harder the QTC is squeezed, the more it conducts electricity, and the faster the motor will run. In this way, it behaves as an infinitely variable resistor.The kit includes pieces of QTC, connecting wires, and an electric motor. Full instructions are provided, which allow you to carry out various experiments with this unusual material.It is a rubber like material, and can be made to different specifications so that it is sensitive to a lighter finger-touch or to very large forces.People who bought this item also bought:
This kit allows you to build a high performance FM mono radio. It is based on the TDA 7000 chip, which comes on a printed circuit board (PCB) containing all the electronic components, which are pre-wired. Building the radio requires the addition of five external components - battery clip, loudspeaker, tuning control, volume control and arial, all of which are contained within the kit.A complete working radio can be assembled from the parts in this kit. You will need to supply a soldering iron, and a battery. A case for the radio is not included, and you might like to design your own case for the radio. The kit comes complete with all the parts required to build the radio, including full instructions.People who bought this item also bought:
This cardboard self assembly kit allows you to make a working sextant, and then learn how to use it in astronavigation. High quality printed and pre-punched cardboard, mirrors and solar filter included. You will need to supply the glue. For years, this was part of the essential equipment on every ship, which helped the process of navigation.Essentially a sextant allows you to work out the height of a celestial object, typically the sun, above the marine horizon, in degrees. By 'shooting the sun' as it is called, you can determine the point when the sun is at its highest, which is local noon, and also how high the sun is above the horizon in degrees, which allows you to work out your latitude.People who bought this item also bought:
This unusual 3D Greeting Card comes with a blank front cover - blank except that it is covered with a grid of hearts. Your job is to use a black pen and to create your own personalised message on the card.When you then view the card with the 3D glasses, the message appears to float in front of the background of hearts.Each set comes with a blank card, a pair of 3D glasses and an envelope.£2.25 each, but £1.99 each if you buy 3 or more.People who bought this item also bought:
This apparently dead and dried up plant comes to life as soon as you place it in water, unfurling into a vigorous green fern. When you remove the water, it quickly dries up again, going back to its dormant state. The cycle can be repeated endlessly. A present for someone curious about the natural world, maybe, or possibly for someone who is a terrible gardener - this is one plant you cannot kill!People who bought this item also bought:
