Shifted to a new room in the hostel for the new academic year and still something was missing. A penstand on my desk!! Why go shop when you can create one yourself...??
Diagrams and CP coming soon. Keep checking...

Book Mark - A better photo.
This is by far one of the best models I've made. I'm nearly obsessed with it.... I call it kirigamic representation of an origami tessellation.
It's a new beginning....I'm soon gonna try it out with other tessellations too... :D

Sunken Sonobe
Thanks to Kalami for the diagrams here.
This is very similar to this model. In fact, the geometry is exactly the same, but the vertices are turned half way down...

Hexgrids-Printed!!
The most tiring job in origami is probably the pre-creasing, especially the hex grid. I've tried to get the hex grid the "conventional way" i.e. using geometry etc..... but the lines became curves and there are hardly any triangles. So I had to get these printed to have more fun...
Sonobe Polyhedron
It's a cute little ball like polyhedron play with. It's even sturdy enough to play catch for quite some time.
Now getting to the geeky stuff about it: It's a 30 piece modular. The skeleton of the structure is a dodecahedron. Each pentagonal face supports a pyramid and hence the puffy shape.

Computer and Origami!!
The CP for my radial corrugation.
This has been rendered using the open source "Processing". I came across it just last night and found it really helpful.
This below is the source code for it:
float r,x1,x2,y1,y2,x3,y3,a=0.55,b=0.65;
int i;
float theta,theta1;
void setup(){
size(350,350);
smooth();
r=340.0f;
}
void draw() {
background(255);
translate(width,height);
for(i=0;i<72;i++) {
theta=i*2*3.14/72;
theta1=(i+1)*6.28/72;
x2=r*sin(theta);
y2=r*cos(theta);
x3=r*sin(theta1);
y3=r*cos(theta1);
x1=x2*0.2;
y1=y2*0.2;
stroke(#ffff00);
line(x1,y1,x2,y2);
stroke(0);
line(x1,y1,0.2*x3,0.2*y3);
line(x2,y2,x3,y3);
if(i%4==1) {
stroke(#00ff00);
line(a*x2,a*y2,b*x3,b*y3);
line(x1,y1,a*x2,a*y2);
}
if(i%4==2) {
stroke(#00ff00);
line(b*x2,b*y2,b*x3,b*y3);
line(b*x2,b*y2,x2,y2);
}
if(i%4==3) {
stroke(#00ff00);
line(b*x2,b*y2,a*x3,a*y3);

Hybrid
This is a hybrid of The spring and the corrugation I made recently. I'm not satisfied with the finish though. I'll have to work out a better one again sometime.
