Bitwise ๐Ÿ“ผ Liminal – A Short Film in 256 Bytes

I found an old VHS tape at a yard sale. It was labeled “Bitwise Liminal” in sharpie. But when I watched the video it was only static.

Then I started having vivid and… unsettling dreams. Also I couldn’t stop thinking about that weird VHS tape.

After researching I learned it was a digital backup. Using some special software I recovered the data. To my shock, it was a 256 byte program…

With trembling hands I opened it in a web browser. Strange. This reminds me of the dreams I’ve been having.

Now I don’t need to sleep anymore. I just keep watching.

LittleJS Engine – Community Game Showcase

It’s been over 2 years since the LittleJS engine was launched and it is still going strong! There have been improvements across the board to make the engine super tight and powerful. To name a few, post processing effects, native wave/mp3 support, typescript compatibility, and NodeJS build system. I also produced a nice intro tutorial to help onboard new users.

In this video we are celebrating some outstanding games made by the community. It is wonderful to see such impressive variety of style and genera in this collection. Here’s to the continued success and boundless potential of LittleJS. Full steam ahead, Choo Choo!

FxVase – Interactive Pottery Simulation

Sculpt, glaze, and fire your own virtual pottery, then mint it on the blockchain to share with the world! This interactive tool allows for a wide range of expressive sculptures to be rendered in real time and saved in HD. It was written from scratch with vanilla JS and webgl shaders using a rendering technique called ray marching.

Free Workshop: How to make amazing generative art with simple JavaScript code

My workshop from last year’s JS Game Dev Summit is now available for free! This three hour course starts with how to create a basic HTML file and goes to advanced graphical effects by the end. It was recorded live with a class that participated by asking questions which helped guide the talk. It’s a great introduction to making generative art and learning how it works even if you’ve never programmed before!

How I made a 1K Pinball Game in JavaScript – Lu1ky Pinball

I’ve made quite a few 1k games now, yet I always find room for improvement and there is so much more to explore in this space. For the JS1024 contest this year the theme was Lucky and I made a tiny pinball machine. It received 1st place in the JavaScript category! I have been wondering for a while how realistic of a pinball sim could be achieved with such a limited amount of code.

This post will walk you through every line for my tiny pinball game that fits in 1 kilobyte of JavaScript. How much is 1k you ask? This much…

for(_='00F*rE8F-7ED/f)*hCin(BMath.AAsB@keyZ1,Y0,XXYWr=V),UUVT-rS69R15Qe. a.f- r-r-=()**Acos(x,y,t, w x ge=n[--;)for();209+=+rw(482(2*h-1)EU+*(1,X9))60	n[h] y=a=>n[Z]=h=2;h*,;rU5Fc.beginPath(c.fill(c.arc(w=(V9)=>n.push({r,g:Xw:0}n=[x=3,1],i=g=X1e3T65{);RY79XX6)}{,816,18WQ+	12W45+	24W45U-21032W70T1Q5F+D+182539,YQT	673,D+*r/38U-*@r/38)V19+Q4R7-754-4EUR7+3FUR0-3E,Y5%3*24438S%9*2W5)}onZdownYonZupXsetInterval(`w=9;w{=Amax(-YAmBYn["zx"[h]]?-.07:.05)T653+65*h],=-+(=482+*(80S/2))U=-+(=7	*@/2)U VQS/8,133],=AmB790,=n.c?.05:@++i)/99+(7	-)/19);width|=2],,.F17,1e3<&&x&&(>{w||x,y,b?--b+r:rUf=Ahypot(y=-x,o=-yTg-,t=w-,0>&0<r*y+t*o&!(t&!)&&(y/f,o/f,f*=f/(t*yS*oUh=!t|b?1.3:(b=9,	0<y||(++g%64||++xU1.7U(r+oC,(t-yC)}))}Vg+8>>32	S%8*2X420+3E,r?9:g%8Vx7	,420+	E,25)`,16)';G=/[- Q-Z@-F]/.exec(_);)with(_.split(G))_=join(shift());eval(_)

That’s how the code looks after being fully minified, though no one would be expected to recognize it at that point. In addition to being minified, it has also been regpacked which is a special tool for size coding that can create compressed JavaScript code that can uncompress itself.

What does it all mean? Keep reading to find out.

LittleJS Breakout Tutorial

This video walks you through how to make a small game from scratch with the LittleJS open source game engine. It covers graphics, sound, input, effects, and gameplay.

We will make a breakout style game with a player controllable paddle, a ball that bounces, and bricks that break when hit. This is a great introduction to LittleJS and takes only around 30 minutes to complete. The tutorial is also available on GitHub for you to follow along.

Scribbobbles at Proof of X in Tokyo

My first generative art project with customizable parameters explores a glitchy circle packing algorithm with a hand drawn aesthetic. It being featured at the Proof of X art exhibition in Tokyo Japan!

Visitors of the exhibition can mint the piece live and personalize their result by adjusting parameters to control color and style. It’s fun to seeing what other people come up with.

Live Minting in Tokyo Japan

Everything was created in vanilla JavaScript, no external libraries used. I first posted a work in progress for this piece almost a year ago in last September! After sitting in my unfinished folder for almost a year, it feels so good to put this one out into the world!

My Artist Story – A Short Autobiography

I was born in the city of Philadelphia and we moved to a suburb while still in elementary school. I lived with my parents and younger siblings, two brothers and a sister. From as early as I can remember I was interested in art and my parents did their best to encourage my creativity. Though money was always difficult in my family, they made sure I had plenty of art supplies and even sent me to special classes at the Philadelphia Art Institute.
