Apology Regarding My Portfolio Website

A few days ago, I built, published, and shared this website online.

In doing so, I made three serious mistakes.

1. I copied another website’s visual style without permission or proper credit.

I was too lazy to design the site from scratch. I assumed that only a few people would see my post or visit the website, so I browsed Awwwards and found this site:

https://farfromhere.emmitfenn.com

I really liked it and decided that it would be “cool” to recreate the same style.

This was the exact prompt I used when I started the project:

“https://farfromhere.emmitfenn.com 音楽要素なくていいけど、これ参考に僕のポートフォリオサイト作りたい 立体のオブジェクトと二次元的模様を行き来する体験を再現したい 単に「カラフルな幾何学オブジェクトが中央にある」のではなく、複数の要素がひとつの彫刻を構成し、視点を回転・ズームして特定の角度に合わせると、隠れていた平面的な模様が成立するアナモルフォーシスが体験の本体です 一度こちらで最終的な2次元の模様を作ったので、それを使って まずどう実装するか練った上で教えて”

English translation

“https://farfromhere.emmitfenn.com I do not need the musical elements, but I want to create my portfolio website based on this site. I want to recreate the experience of moving back and forth between three-dimensional objects and two-dimensional patterns. The main experience is not simply having a colorful geometric object in the center. Rather, multiple elements form a single sculpture, and when the viewer rotates and zooms the perspective to a specific angle, a previously hidden flat pattern comes together through anamorphosis. I have already created the final two-dimensional pattern, so I want to use it. First, think through how this could be implemented, and then explain it to me.”

I intentionally tried to reproduce its concept and visual experience.

2. I failed to acknowledge what I had done.

At the very least, I should have clearly credited the original work and explained that my website was heavily based on it. Instead, even after my post received a lot of attention, I stayed silent and continued to present the project as though I had designed it entirely from scratch.

3. I took too long to apologize publicly.

After people began pointing out the similarities between the two websites, I should have removed the copied design and addressed the situation publicly without delay.

I contacted Raphaël Améaume privately to apologize. Regardless, I should have acknowledged the issue publicly sooner.

The copied design has now been removed from the website. The WebGL rendering is currently turned off and you will only see the simple html and css. I will replace it with a new design created entirely by me.

I am sorry to Raphaël Améaume, DotDotDash, Emmit Fenn, everyone else involved in creating Far From Here, and everyone who saw, supported, or shared my work under the impression that the concept and design were my own.

I will keep the original promotional post available as a public record, but I will add this apology and the necessary context prominently so that the project is no longer mistaken for my original design.

From now on, I will properly credit my sources, seek permission when necessary, and clearly distinguish between inspiration, reference, technical study, and original work, even for small or personal projects.

Building this portfolio

A short note on turning four flat patterns into one navigable three-dimensional object.

Today I finished the first version of this portfolio. It begins with one three-dimensional sculpture that resolves into four graphic patterns from four different viewpoints.

Hope you'll enjoy it:D
