Howdy, folks! Today we will be looking at the JavaScript code behind this amazing 3D tunnel effect. This code has an interesting lineage so we’ll also talk about some of the history behind it. for(c.width|=k=i=960;z=–i;x.fillStyle=`hsl(0 99%${i/9}%`)x.fillRect(k-z*C(j=i/k+t/4)+S(m=k*j)*(r=1e5/z),540+C(m)*r-z*S(j),s=3e4/z*S(j*9),s) Continue reading on for … Continue reading →

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 →
