Today we will dissect the tiny JavaScript code that draws a parallax background with mountains and sky. This simple code can be used as a base to create different types of background scenes for your game or website. for(w=i=99;i–;)for(j=0;j<9;x.fillRect(i*20,j++?w*j+w+w*C(q/9)/j+59*C(q/3.9)/j:0,20,3e3))q=(j*w+i+t*j**3),x.fillStyle=R(9+j*40%w,j*20,w-j*9) Continue … Continue reading →

Today we will examine the JavaScript code to make this awesome shatter effect. The concepts demonstrated by this dweet can be used for making a variety of cool effects. In one of my previous posts I showed a similar technique … Continue reading →

The dweet we will be looking at today may be the simplest one so far, but it’s every bit as mesmerizing and uses a neat trick to plot polar coordinates. There is plenty of room for playing around with the … Continue reading →

Today we will be examining my most popular dweet, a miniature black hole simulation! It’s one of my easiest dweets to explain and the code is fairly straightforward. Read on for a full analysis… for(i=0;i<2e3;x.fillRect(i?960+i*S(F=260*(t+9)/i+S(i*i)):0,i?500+.2*(2*i*C(F)+2e4/i):0,K=i++?S(i)*9:2e3,K))x.fillStyle=R(99*i,2*i,i,i?1:.4)

Today we will be examining this crazy small JavaScript program that generates an array of endless random spirograph designs. Read on for a full explanation of how it works. for(i=144;q=(8+t>>3)*i–;x.fillRect(i%16*120+T(S),(i>>4)*120+T(C),2,2))t%24<1?c.width|=r=n=>S(q**n)*9|0:T=f=>5*r(4)*f(r(3)*t)+9*f(r(2)*t)+60

This is the first in a series of posts where I will analyze a dweet’s code, explain how it works, and why it was done that way. A dweet is a 140 character JavaScript program published on Dwitter. The goal … Continue reading →
