At equilibrium, the center of mass and the contact point are on the line perpendicular to the ground. Not only does it have a low center of mass, but it also has a specific shape. A more common example is the Comeback Kid, Weeble or roly-poly toy (see left figure). (The previously known monostatic polyhedron does not qualify, as it has several unstable equilibria.) A sphere weighted so that its center of mass is shifted from the geometrical center is a mono-monostatic body however, it is not homogeneous. In geometry, a body with a single stable resting position is called monostatic, and the term mono-monostatic has been coined to describe a body which additionally has only one unstable point of balance. When a roly-poly toy is pushed, the height of the center of mass rises from the green line to the orange line, and the center of mass is no longer over the point of contact with the ground. Copies of the Gömböc have been donated to institutions and museums, and the largest one was presented at the World Expo 2010 in Shanghai, China. Its shape helped to explain the body structure of some tortoises in relation to their ability to return to equilibrium position after being placed upside down. It has a sharpened top, as shown in the photo. Gömböc is the first mono-monostatic shape which has been constructed physically.
Mono-monostatic shapes exist in countless varieties, most of which are close to a sphere and all with a very strict shape tolerance (about one part in a thousand). The existence of this class was conjectured by the Russian mathematician Vladimir Arnold in 1995 and proven in 2006 by the Hungarian scientists Gábor Domokos and Péter Várkonyi by constructing at first a mathematical example and subsequently a physical example. The Gömböc ( Hungarian: ) is the first known physical example of a class of convex three-dimensional homogeneous bodies, called mono-monostatic, which, when resting on a flat surface have just one stable and one unstable point of equilibrium. Most people like Arkanoid or similar, and since you can’t go wrong with a first-person puzzle that that also features freerunning elements this game might be a blend of flavors which you've been looking for.4.5 m (15 ft) gömböc statue in the Corvin Quarter in Budapest 2017 A unique blend that you have to tryĮquilibrium 3D is a game that is unusual yet it makes perfect sense. After all, Equilibrium 3D looks really good and gameplay is sufficiently tricky to be both challenging and enjoyable. It makes sure you use one of the game’s core mechanics and that can’t be a bad thing. That however, doesn’t even come close to being a game-breaker. For example, in the FPS game, there are some metal crates on which you can’t jump, thus the game forces you to use the cube creating gun all the time. An interesting start to something that might turn out to be greatĮquilibrium 3D is in its early stages of development so some bugs can be expected, and some things might not make sense. Placing blocks in the three-dimensional space is vital because you will have to use them and your freerunning skills to reach the detonator.
The catch is that you will have to explore the interior of a block in order to find a detonator which after you activate, destroys it in the Arkanoid-style game. You get a gun but it’s not for blasting blocks, you actually use it to create them. This mode sets you up for an entirely different kind of game. Some of them have different kinds of power-ups that can be used to your advantage in cleaning the level faster but there are others which once hit, transform the game into a FPS. In Equilibrium 3D you start off destroying blocks like in Arkanoid, using a ball and a paddle that can only be moved on a horizontal axis. Simple gameplay that’s actually not all that simple, but it’s fun
Equilibrium 3D is a nice experiment that fuses an arcader with Arkanoid gameplay and a freerunning/puzzle first-person shooter to create a game that challenges you on multiple fronts.
