Free curves downloads

Make many beautiful relaxing animations based on Spirograph and Lissajous patterns, taken into 3D. You can use any pictures as textures to wrap over the patterns - then as the curves animate, your pictures can twist and turn like reflections in a hall of mirrors! The original 2D Lissajous patterns in the 19th century used a beam of light reflected from mirrors attached to two tuning forks. Lissajous 3D traces the curves using a ribbon, or a tube. By using vibrations in three or more directions, these patterns become 3D. You can use the example patterns or the randomiser as a starting point. By varying the ribbon, material, lighting, transparency, frequencies and other options you can make them into new patterns of your own. Comes with a screen saver to show your animations, with any music as background (mp3, wav etc). It can also select tunes at random from a folder or cd. You can set the patterns to respond to chords played in the companion program Tune Smithy, and the other way round, the fractal tunes can acompany the screensaver. Many pattern transforming effects, some related to things that happen with real world Lissajous patterns, - pattern drift so they continually change shape, gravity, magnet, inversion (turn inside out), friction, etc. Also you can make spirographs - those patterns made by rolling wheels within each other - this is the same idea but taken into 3D. Features include, as well as the textures, materials, transparency, colour ripples, and various forms of ribbon or tube including star cross section tubes, twisting tubes and bead effects, strings of spheres, and ribbons with ripples. Fog can be added as well depending on the distance into the shape - so you can have shapes that disappear in and out of the mist. Also you can make curves that spiral around themselves as they trace the Lissajous curve.The patterns can be exported as movies, image frames or 3D animations in the Obj file format recognised by many 3D programs.

SeriousBit Ellipter is a .NET library for licensing shareware applications and components based on Elliptic Curves Asymmetric Cryptography. Using a new and strong security technology we provide software developers and publishers with an unprecedented level of protection. With our library you can create or verify secure product keys in just 3 lines of code!

With Ellipter you can:
- Protects your .NET 2.0 (and later) based applications and components
- Programatically create and verify secure product keys
- Easily verify any key with Ellipter's integrated UI
- Create thousands of keys in just two clicks.

Ellipter's Features:
- Strong Encryption - SEL uses an asymmetric elliptic curves encryption algorithm to create and verify license keys which makes it impossible for a cracker to create any keygens by reverse-engineering your code or even having full access to it.
- Compact Product Keys – SEL product keys are as short as possible: 29 characters length when no product info is embedded.
- ID Based License Keys - Each generated license key contains an ID which guarantees license key uniqueness and allows identifying of license keys.
- Embedded Product Info - Additional product information can be embedded into license keys when they are generated which can be used for specific software features.
User Interface - SEL has a full featured User Interface with Public/Private keys pair Generator, Serials Generator and Serials Validator.
- Royalty Free - licensed per developer. You can build as many applications as you want and distribute them without paying any further royalties.
- Easy to Use - SEL’s simplicity of use is just outstanding: you need to write just 3 lines of code to have it done.
- C# and Visual Basic examples

Organic Studio is a procedural vector editor which uses powerful envelopes put around simple shapes to produce complex-looking shapes that are still easy to edit. In addition, Organic Studio provides a unique and powerful along-the-path instancing tool, which takes one or several shapes and places them along the outline of any object in the program, with various user-adjustable settings. Once created, the editor allows shapes to be shaded with solid, linear, radial, or center-out gradient, as well as a powerful bitmap fill, and then exported to another graphics application either through AI or SVG formats, or as a rendered bitmap.
