Lawrie Cape

I'm Lawrie, a creative front-end and javascript developer.

Over the last 10 years, I have worked for a number of top UK digital agencies, producing work for many high profile brands and companies. I have a wealth of technical skills, and take a keen interest in UI, UX, creative ideas and innovative uses of technology. I'm proactive and an enthusiastic learner, always on the lookout for challenging projects and eager to learn and expand my skillset.

I am currently a Senior Front-End Developer at Equator, an industry leading digital agency in Glasgow. My role involves the planning and production of large development projects for a wide variety of clients, such as Axa, Beazley and Vitality Health, team support and development, rapid prototyping and maintenance of long term projects.

I work with a variety of modern development tools and languages, including -

  • HTML (Including JSX, Handlebars, Liquid and Markdown templating etc.)
  • CSS (CSS3, Sass, Less, BEM, SMACSS)
  • JavaScript (Vanilla JS, ES6, classes, prototypes, jQuery)
  • React & Redux
  • Build tools (NPM, Grunt, Gulp, Webpack etc.)
  • Responsive design and progressive enhancement
  • Accessibility and performance optimisation
  • Version control using Git and SVN
  • Adobe Creative Suite (Photoshop, Illustrator, Premiere, Audition etc.)
  • Canvas and WebGL (Pixi, ThreeJS)
  • Animation libraries (GSAP, AnimeJS)
  • Experiential web technologies - Microphone and camera access, webMIDI, 3d webAudio, web VR / AR etc.
  • Documentation (Readme, Confluence, JS Docs, Living Styleguides)
  • Project management tools and workflows (Waterfall, Scrum, Agile, Jira workflow, Trello etc. )

Unfortunately, I'm unable to show a number of my recent client projects publicly. For access to my full portfolio site, please email me.

Below you will find a selection of my favourite personal projects.


Gigfi is a web app for creating and playing Spotify playlists, which are populated with songs by bands who will soon be playing in your city, no matter where in the world you are.

I planned the core concept, built the initial prototype and wrote the backend functionality, and collaborated with two colleagues on the design and front end build.

The site has garnered high praise, receiving 50,000 visits within 24 hours of launch. It reached the front page of Reddit and has been featured on Fast Company, BuzzFeed and BBC News.

“A simple, powerful mashup is the best thing to happen to music on the internet in a little while.”

Unfortunately, due to recent LastFM API changes, the site no longer functions.


Scales is a React based web app designed to help visualise and experiment with music scales across a variety of tunings and instruments.

Scales uses -

  • React
  • React Router
  • WebAudio
  • WebMidi input & output
  • Anime JS
  • LocalStorage API
  • Sass
  • Netlify continous deployments

Note: This is a proof of concept and is pending a full UX and design overhaul upon partnership with a designer.


Rompola is an informal 3d sketching environment running directly in the browser.

Built using webGL (through threeJS), TweenLite, PreloadJS and EaselJS, Rompola is a expressive and fun to use drawing app.

Draw with your left mouse button and rotate the stage with the right. You can zoom and pan using your mouse wheel, and there are numerous other options to play with, which allow you to create a wide variety of styles and effects. The project was featured on Google's Chrome Experiments site.

Tangent Spaces

After discovering the beautiful geometric designs created by graphic designer Tilman Zitzmann for his Geometry Daily project, I was inspired to see how I could recreate them, and bring them to life.

Tangent Spaces is an open source project which explores the designs using various interactive web technologies.

Tangent Spaces uses PixiJS's 2d rendering engine for super-fast webGL rendering, with a canvas fallback where necessary, and is featured on the official PixiJS showcase.

“This is so awesome, it’s ridiculous!!”

Cellular AutoMidi & Flash Midi Server

To explore the intersection between generative systems and music, I developed Cellular AutoMidi, an audio application, which creates music based on a modified Cellular Automata algorithm.

Designed to be enigmatic but playful, Cellular AutoMidi was released as an open source project and was featured on the influential music production blog Create Digital Music

To extend the creative possibilities of the application, I developed Flash Midi Server, a Processing application and Flash library to allow AS3 applications to both send and receive midi signals.

This allows generative audio applications (such as Cellular AutoMidi) to play music using software or hardware audio equipment - vastly increasing the possible sounds. It also allows hardware midi controllers to be used as input devices for Flash applications.

Creative coding & generative arts

I’m fascinated by creative coding, generative arts and emergent behaviours, which feeds into many of my personal projects.

Feedback Cam is a recent project, which uses cutting edge web technologies (webGL, webRTC streaming video and fragment shaders) to explore the beautiful and complex patterns that emerge from recursive video loops.

Wiblr is an experiment that uses concentric circles, a simple physics system and webGL as a novel interface for photographic manipulation. It allows users to upload an image, or take on from their phone camera directly in the browser, then lets them warp and deform it in fun ways. The project was featured on Google's Chrome Experiments site. A simplified version of Wiblr was featured on the CodePen homepage.

inParticular is a project which uses some basic mathematical formulas and randomisation to create highly complex 3d formulaic geometries. These patterns are then processed with webgl shaders, leading to very striking and diverse images.

WebMidi Typography is an project experimenting with web technologies and physical interfaces. An input device, originally designed for audio manipulation, is repurposed to interact with a web project using the WebMidi api. Typographic settings such as heading and body fonts, colours, sizes, kerning, leading and alignment are customized in real time. The tactile nature of the inputs the device offers and the instant feedback makes experimenting a rapid and enjoyable process.

Following this project, I was contacted by Gor Jihanian, a professional type designer. I shared the code with him, and helped customise it to his needs. His work built upon the project was then presented in New York at Typographics 2018 - a design festival for people who use type.
