Just throwing something out there. A very simple branch algorithm. Was originally annoyingly fractal so I added flowers.
link to http://www.onager.org/~dnolen/masha-arbor.jpg to see the image.
comments/criticism/suggestions welcome.

Thanks, the color is what I'm happiest about- just trying to express the familiar in an (hopefully) elegant fashion. Apologies, I just linked the final image. Here is the source:
//globals
boolean done=false, grabbed=false, base=true, lastone=true;
float rvalue = 60, gvalue = 30;
float ginc1, ginc2, rinc;
int counter=0, counter2=0;
float xsize=30;
float ysize=100;
float ratio=1.25;
float grain=20;
float flstart=((ysize-grain)/3)+grain;
void setup() {
//noFill();
noStroke();
smooth();
float tempsize = ysize;
size(1152, 76 ;
for(int i=0; tempsize > grain; i++) {
counter++;
tempsize/=ratio;
}
println(counter);
rinc = (170-60)/(counter/2.0);
ginc1 = (80-30)/(counter/2.0);
ginc2 = (220-80)/(counter/2.0);
//println(rinc + " " + ginc1 + " " + ginc2);
background(255, 255, 110);
}
void loop() {
if(!done)
drawArbor(xsize, ysize, 0, rvalue, gvalue);
else if(!grabbed) {
grabbed = true;
saveFrame();
} else
;
}
void drawArbor(float rectxSize, float rectySize, float angle, float rval, float gval) {
float ny, lefta, righta;
if(base) {
translate(width-(width/2), height-(height/);
rotateZ(PI);
base = false;
}
if(rectySize>grain) {
//stroke(rval, gval, 0);
fill(rval, gval, 0);
//println(rval + " " + gval);
if((rval+rinc) < 170) { //set branch color
rval += rinc;
gval += ginc1;
//println("adding ginc1");
}
else if((gval+ginc2) < 220) {
gval += ginc2;
//println("adding ginc2");
}
rectMode(CENTER_DIAMETER);
//translate(x,y);
rotate(angle); //rotate at pivot
ny = (ysize*.95)/2;
/*if(rectySize>1
ny = rectySize*.95;
else
ny = (ysize*.95)/2;*/
//println(x + " " + ny + " " + rectxSize + " " + rectySize);
rect(0, ny, rectxSize, rectySize); //draw rect
translate(0, ny);
//flower variation for masha
/*if(rectySize < flstart) {
float myRan;
myRan = random(0, 10);
if(myRan>=9.0) {
push();
drawBlossom(rectySize, ny);
pop();
}
}*/
lefta = random(-PI/4, 0); //set angles for next two branches
righta = random(0, PI/4);
push(); //I am very afraid
drawArbor(rectxSize/ratio, rectySize/ratio, lefta, rval, gval);
pop();
push();
drawArbor(rectxSize/ratio, rectySize/ratio, righta, rval, gval);
pop();
} else
done = true;
}
void drawBlossom(float rysize, float center) {
//float petal1ang, petal2ang, petal3ang, petal4ang, petal5ang;
float randang, gran;
for(int i=0; i<6; i++) {
gran = random(60, 200);
fill(255, (int)gran, 210);
randang = random(-PI, PI);
rotateZ(randang);
rect(0, 0, rysize*.8, rysize*1.5);
}
}
