Experience

Swirl Holiday Card

The team decided that we would create a 3D interactive experience with Three.js as a base. Each year, we would create a holiday card that we'd send out to clients and then allow them to pick a charity that we would then donate to on their behalf.

We utilized Preact as a base, but the main 3D component was built using Three.js. The 3D assets were built in VR using an HTC Vive and Google blocks that were then imported into Three.js.

Sound Reactivity Module

This is a module that I reuse for many of my audio-reactive visuals. It lets me quickly get sound data for any object I want to react to visually. This version is a simple ES6 class; I will continue to evolve this project as needed.

VIVEPORT Mailchimp Email Template

Working with HTC to improve their newsletter process, I developed this dynamic Mailchimp template system. Utilizing the Foundation 2 for the email framework allowed me to build a rather complex and completely customizable template that enabled the output of any of the various types of weekly newsletters that they had been doing.

Sovos Brands Website

We built a responsive WordPress-based site using the Visual Composer plugin to create an easy-to-edit, good-looking web experience. Utilizing the Visual Composer plugin allowed us to quickly build a robust and usable site.

Honey 10th Year Anniversary Visualization

https://vectorclash.github.io/honey-10/

I developed this audio-reactive visualization for the Honey Soundsystem 10th anniversary party. It was projected in nine hours on the upstairs dance floor at Public Works here in San Francisco. I used Three.js for this project.

Background Gradient Plane Component

This ES6 JavaScript class was built for my portfolio site. It allows me to generate a color-shifting plane with a dynamic gradient material. As each frame is updated, the colors change, and a new canvas object is generated to create the gradient texture, which is then passed along to a Three.js material as bitmap data.

Nylas Homepage Animation

http://www.nylas.com

This project aimed to create an engaging and fun animation to be showcased on the homepage. The animation was built using SVG assets to maintain a crisp and clean visual style and then animated using the GreenSock Animation Platform (GSAP).
