Veins and Scribbler

Treatkor mentioned levitated.net in a post about Chaoswarp’s Box Fitting entry, which in itself is quite cool. After having a look around I was inspired to recreate [URL=“http://levitated.net/daily/levMainVein.html”]‘Main Vein’ in 25 lines.

My first attempt yielded different results to what I was aiming for, but I liked it anyway!

Scribbler:

_global.oldPoint = new Object();
_global.oldPoint.x = _global.oldPoint.y=0;
_global.branches = [null];
_root.createEmptyMovieClip("slate_mc", 1).onEnterFrame = function() {
    //this.lineStyle(Math.round(Math.random()*10), (Math.random()*0xFFFFFF), 100);
    var point:Object = {x:(Math.random()*Stage.width/20)+(_global.oldPoint.x)-(Math.random()*20), y:(Math.random()*Stage.height/20)+(_global.oldPoint.y)-(Math.random()*20)};
    this.lineTo(point.x, point.y);
    _global.oldPoint = point;
    (Math.random()>0.95) ? this.lineStyle(Math.round(Math.random()*10), (Math.random()*0xFFFFFF), 100) : null;
    if (!dragging) {
        this._x = (Stage.width/2-point.x);
        this._y = (Stage.height/2-point.y);
    }
};
_root.slate_mc.onMouseDown = function() {
    this.startDrag();
    dragging = true;
};
_root.slate_mc.onMouseUp = function() {
    this.stopDrag();
    dragging = false;
};

_root.createEmptyMovieClip("slate_mc", 1).lineStyle(3, 0xFF0000, 100);
_root.slate_mc.activeFrame = _root.slate_mc.count=0;

    _global.oldPoint = point;
    (Math.random()>0.9) ? this.count=drawBranch(this, this.count, point) : null;
    this.activeFrame = 0;
};
function drawBranch(obj, count, point) {
    (count>=10) ? count=0 : count++;
    obj.createEmptyMovieClip("branch"+count, count)._x = point.x;
    obj["branch"+count]._y = point.y;
    obj["branch"+count]._rotation = (Math.random()*270)-45;
    obj["branch"+count].steps = 1;
    obj["branch"+count].lineStyle(1, 0xCC0000, 100);
    obj["branch"+count].onEnterFrame = function() {
