The Prime Number Spiral (a.k.a. the Ulam Spiral) is formed by marking the prime numbers in a spiral arrangement of the natural numbers. This is software is for exploring the Prime Number Spiral.
The calculation is intended for the purposes of geometric and strength designs of spiral cylindrical torsion springs made of wires and rods in circular sections, loaded with a static or cyclic loading. Application is developed in MS Excel, is multi-language and supports Imperial and Metric units. Is based on ANSI, ISO and DIN standards and support many 2D and 3D CAD systems.
SurfTris is a Tetris clone with a new twist. Instead of 2D plane, playing field is spread upon a 3D surface. There are five different surfaces to choose from: three closed surfaces - Cylinder, Cone, and Hyperboloid and two twisted planes - C-Spiral and O-Spiral. Game features: - Unique challenges of Twisted and Diversity Modes - Ability to use MP3 and MIDI files of gamer’s choice as game soundtrack - High Score tracking for every surface.
Semi-psychedelic screensaver takes your screen for a spin. The screen is filled with rotating tiles that slowly start to spiral. You can set speed, frequency, size and separate colour channels. New in v1.4 is the One big disk option.
Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It's released under the GNU General Public License which makes it free. It uses Newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns.
Enjoy infinite light show on your screen. The movements of the shine balls that flash and grow from the center create lovely chaos on your screen that can mystify your mind. The spiral rotation in the background just contributes. This simple 3D animation makes great cyber look and feel of Mystify Flashing ScreenSaver.
The calculation is intended for the purposes of geometric and strength designs of metal springs of various types and designs (15 types), subjected to static or cyclic loads. Application is developed in MS Excel, is multi-language and supports Imperial and Metric units. Is based on ANSI, ISO and DIN standards.
Genetica 2 is a node-based seamless texture editor with more than 500 texture presets, automatic seamlessness, and resolution-independence. New in this version is a Substance Lab that helps you quickly create new textures, a new Weather Lab for applying aging effects to your textures, a new Cut & Tile Lab that can automatically turn materials into everything from wall tiles to floor boards, and much, much more. Also comes in a Pro edition.
Rhumb Line, original 2-player strategy game of observation and placement on a compass rose board. Officer yellow and Sailor blue stones are placed, one at a time, building and/or blocking point-scoring rhumb line combinations. The object is to out-navigate the opposition and score the most points to rule the waves. 4 same-color stones in a radius is 10 points, an arc 20 points and a spiral 30 points.
