Open Hexagon is a free open-source clone of the game "Super Hexagon by Terry Cavanagh".
Gameplay is easy to learn but hard to master.
You control a triangle that rotates around the center of the screen.
Your goal is to stay alive as long as possible by avoiding the walls that go towards the center.
Features JSON and LUA scripting for complete customization and level sharing.

Open Hexagon was developed with the goal of being open. Players can create their own levels by using the simple yet powerful Lua scripting language. The amount of freedom that level designers have is unprecedented: keep your levels simple, or go wild and implement brand new mechanics and even entire new games! If you have never coded before, Open Hexagon can be a great (and fun) introduction to programming.
Play the game the way you want to. Speed up or slow down levels. Change the colors and the way the environments are rendered. Open Hexagon gives players the freedom to customize their game just the way they like to. Or take it one step further and modify the game engine itself, as it is fully open-source.
The game is a nearly exact open code copy of the great Super Hexagon from Terry Cavanagh, one of the most reputed independent developers at this moment. It offers a nearly identical playability with the difference that it has additional difficulty modalities and a bit worse music.
Uptodown is a multi-platform app store specialized in Android. Our goal is to provide free and open access to a large catalog of apps without restrictions, while providing a legal distribution platform accessible from any browser, and also through its official native app.
This beautiful Bangle bracelet is a reminder that you are loved, protected, and out-of-this-world chic: Think of our hexagon motif as a stylized halo the six sides are a nod to the six-winged angels known as seraphim.
Marblehex seamlessly fuse together the multifaceted, ever changing beauty of natural marble with the most up to date inkjet, porcelain glazing technology.
Our Marblehex products are "double glazed" with an initial inkjet glaze coating followed by a second special glaze used to "open" the veins and create definition with a unique gloss/lustre finish within the veins.
Perfect for wall and floor surfaces throughout the home or any light commercial environment.
Dependence of geometry and pore size for nuclei engagement. HUVECs were cultivated on elongated (a) l7L14-closed microstructures (127 nuclei in 7 structures) and (b) l7L14-open structures (700 nuclei in 15 structures), or on regular open structures with different horizontal dimensions D: (c) D13.5-open (607 nuclei in 6 structures), (d) D10-open (95 nuclei in 1 structure), (e) D8.8-open, (178 nuclei in 4 structures), (f) D6.5-open (94 nuclei in 5 structures), and (g) D4.5-open (77 nuclei in 7 structures). After the 3D segmentation of nuclei, the position of the bottom of the nuclei was determined, with a position of 0 µm corresponding to the contact with the bottom substrate (black horizontal line) and a position of 7 µm to the top of the microstructures (blue horizontal line). For D4.5-open microstructures (g), the highest position compared with the expected height of the structure likely reflects an optical deformation when imaging through a densely polymerized structure. (h) Recapitulative scheme showing nuclei engagement in the function of the pore size and on the closed or open nature of the microstructure.
Recapitulative scheme of the global cell behaviour in the microstructures. (Top) Organisation of endothelial HUVECs in function of the elongation of hexagons in the horizontal plane, and of the open or closed nature of the microstructure. These two characteristics modulate the orientation of the top monolayer, the vertical engagement and the induction of filopodia, and the orientation of the exploratory filopodia. The vertical cell polarization and the induction of filopodia are hallmarks of tip cell phenotype, but occur independently of VEGF. (Bottom) Zoom of the different protrusive modes present in the bottom plane (pillars) of open elongated structures, and transitions between them.
In open microstructures, we observed interconversions between different protrusive modes characteristic for endothelial organization in 3D substrates (Figure 10, bottom). First, an amoeboid mode, probably due to confinement constraints, was occasionally observed. Second and more systematically, a filopodia-based organization was observed, from which could originate dactylopodia-like elongated protrusions (mesenchymal modes). Dactylopodia were reported to play a central role in non-vascular ECM endothelial invasion [35]. Importantly, filopodia and derived protrusions were observed independently on VEGF, suggesting they may be induced by geometry.
We observed that filopodia formation involved transitory contacts with pillars. Mechanisms of stabilization on pillars were reported for fibroblasts near highly flexible hairy silicon nanowires, allowing us to obtain measurements on traction forces exerted by filopodia (in the range of nN) [66]. Although on a different cell type (fibroblasts spontaneously generate many filopodia, contrary to endothelial cells), it is of interest to note that in this study, filopodia exhibited a clear topographical preference for pillar bundles over a flat substrate, with most filopodia tips in contact with flexible pillars, and unstable filopodia on the flat substrate [66]. In our microstructures, we also distinguished two types of filopodia, with longer ones that had a preferential orientation in the principal direction of hexagons in elongated microstructures. The tips of longer filopodia were usually not in contact with a pillar; rather, pillars were tangential to filopodia. This suggests an intermediate stabilization by pillars, giving a general orientation to filopodia during active exploratory events.
