RubySketch is a mobile-friendly environment for graphics programming, equipped with a full scripting-language Ruby interpreter and a built-in text editor that lets you write and run Ruby scripts on the spot. With a graphics API highly compatible with Processing, you can write code as if sketching ideas, and enjoy creating animations, visual expressions, interactive works, or even games-right on your iPhone or iPad. One of its biggest strengths is how easily you can dive in and start building the moment inspiration strikes. Key features: - Embedded Ruby interpreter (CRuby / official MRI implementation) - Processing-compatible graphics API with shader support - Lightweight, easy-to-use text editor - Sprite system with physics support (collision, gravity) - Camera input for image processing - Sound playback support (great for games and effects) - A large set of sample scripts included for immediate use - Comes with a full-featured Klondike Solitaire game! RubySketch also supports a wide range of Processing-compatible functions, making it a versatile tool for learning, creative coding, and playful experimentation: --- abs, acos, alpha, angleMode, applyMatrix, arc, asin, atan, atan2, background, beginContour, beginShape, bezier, bezierDetail, bezierPoint, bezierTangent, bezierVertex, blend, blendMode, blue, brightness, ceil, circle, clear, clip, color, colorMode, constrain, copy, cos, createCanvas, createCapture, createFont, createGraphics, createImage, createShader, createShape, createVector, curve, curveDetail, curvePoint, curveTangent, curveTightness, curveVertex, degrees, deltaTime, displayDensity, displayHeight, displayWidth, dist, doubleClicked, draw, ellipse, ellipseMode, endContour, endShape, exp, fill, filter, floor, focused, frameCount, frameRate, fullScreen, fullscreen, green, height, hue, image, imageMode, key, keyCode, keyIsDown, keyIsPressed, keyPressed, keyReleased, keyTyped, lerp, lerpColor, line, loadFont, loadImage, loadPixels, loadShader, log, loop, mag, map, max, min, motion, motionGravity, mouseButton, mouseClicked, mouseDragged, mouseMoved, mousePressed, mouseReleased, mouseWheel, mouseX, mouseY, noClip, noFill, noLoop, noSmooth, noStroke, noTint, noise, noiseDetail, noiseSeed, norm, pixelDensity, pixelHeight, pixelWidth, pixels, pmouseX, pmouseY, point, pop, popMatrix, popStyle, pow, printMatrix, push, pushMatrix, pushStyle, quad, quadraticVertex, radians, random, randomGaussian, randomSeed, rect, rectMode, red, redraw, renderMode, requestImage, resetMatrix, resetShader, rotate, rotateX, rotateY, rotateZ, round, saturation, save, scale, setTitle, setup, shader, shape, shapeMode, shearX, shearY, sin, size, smooth, sq, sqrt, square, stroke, strokeCap, strokeJoin, strokeWeight, tan, text, textAlign, textAscent, textDescent, textFont, textLeading, textSize, textWidth, texture, textureMode, textureWrap, tint, touchEnded, touchMoved, touchStarted, touches, translate, triangle, updatePixels, vertex, width, windowHeight, windowMove, windowMoved, windowOrientation, windowResizable, windowResize, windowResized, windowWidth, windowX, windowY
