-Assignment 4 - Creative Coding: Interactive Multimedia Experiences
-===
+## Song Visualizer
 
-Due: October 4th, by 11:59 AM.
+https://a4-yasmine-aoua.glitch.me
 
-For this assignment we will focus on client-side development using popular audio/graphics/visualization technologies. The goal of this assignment is to refine our JavaScript knowledge while exploring the multimedia capabilities of the browser.
+The goal of this application was to make a music visualizer that a user could change the color of the visualization, the song, and be able to stop and start the application.

-Baseline Requirements
----
-
-Your application is required to implement the following functionalities:
-
-- A server created using Express. This server can be as simple as needed.
-- A client-side interactive experience using at least one of the following web technologies frameworks.
-  - [Three.js](https://threejs.org/): A library for 3D graphics / VR experiences
-  - [D3.js](https://d3js.org): A library that is primarily used for interactive data visualizations
-  - [Canvas](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API): A 2D raster drawing API included in all modern browsers
-  - [SVG](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API): A 2D vector drawing framework that enables shapes to be defined via XML.
-  - [Web Audio API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API): An API for audio synthesis, analysis, processing, and file playback.
-- A user interface for interaction with your project, which must expose at least four parameters for user control. [tweakpane](https://cocopon.github.io/tweakpane/) is highly recommended for this, but you can also use regular HTML `<input>` tags (the `range` type is useful to create sliders). You might also explore interaction by tracking mouse movement via the `window.onmousemove` event handler in tandem with the `event.clientX` and `event.clientY` properties. Consider using the [Pointer Events API](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_events) to ensure that that both mouse and touch events will both be supported in your app.
-- Your application should display basic documentation for the user interface when the application first loads.
-
-The interactive experience should possess a reasonable level of complexity. Some examples:
-### Three.js
-- A generative algorithm creates simple agents that move through a virtual world. Your interface controls the behavior / appearance of these agents.
-- A simple 3D game... you really want this to be a simple as possible or it will be outside the scope of this assignment.
-- An 3D audio visualization of a song of your choosing. User interaction should control aspects of the visualization. 
-### Canvas
-- Implement a generative algorithm such as [Conway's Game of Life](https://bitstorm.org/gameoflife/) (or 1D cellular automata) and provide interactive controls. Note that the Game of Life has been created by 100s of people using <canvas>; we'll be checking to ensure that your implementation is not a copy of these.
-- Design a 2D audio visualizer of a song of your choosing. User interaction should control visual aspects of the experience. 
-### Web Audio API
-- Create a screen-based musical instrument using the Web Audio API. You can use projects such as [Interface.js](http://charlie-roberts.com/interface/) or [Nexus UI](https://nexus-js.github.io/ui/api/#Piano) to provide common musical interface elements, or use dat.GUI in combination with mouse/touch events (use the Pointer Events API). Your GUI should enable users to control aspects of sound synthesis. If you want to use higher-level instruments instead of the raw WebAudio API sounds, consider trying the instruments provided by [Tone.js]() or [Gibber](https://github.com/charlieroberts/gibber.audio.lib).
-### D3.js
-- Create visualizations using the datasets found at [Awesome JSON Datasets](https://github.com/jdorfman/Awesome-JSON-Datasets). Experiment with providing different visualizations of the same data set, and providing users interactive control over visualization parameters and/or data filtering. Alternatively, create a single visualization with using one of the more complicated techniques shown at [d3js.org](d3js.org) and provide meaningful points of interaction for users.

-Deliverables
----
-
-Do the following to complete this assignment:
-
-1. Implement your project with the above requirements.
-3. Test your project to make sure that when someone goes to your main page on Glitch/Heroku/etc., it displays correctly.
-4. Ensure that your project has the proper naming scheme `a4-firstname-lastname` so we can find it.
-5. Fork this repository and modify the README to the specifications below. *NOTE: If you don't use Glitch for hosting (where we can see the files) then you must include all project files that you author in your repo for this assignment*.
-6. Create and submit a Pull Request to the original repo. Name the pull request using the following template: `a4-firstname-lastname`.
-
-Sample Readme (delete the above when you're ready to submit, and modify the below so with your links and descriptions)
----
-
-## Your Web Application Title
-
-your hosting link e.g. http://a4-charlieroberts.glitch.me
-
-Include a very brief summary of your project here. Images are encouraged when needed, along with concise, high-level text. Be sure to include:
-
-- the goal of the application
-- challenges you faced in realizing the application
-- the instructions you present in the website should be clear enough to use the application, but if you feel any need to provide additional instructions please do so here.
+I faced a couple challenges when creating this project. The first challenge I faced was creating the song picker using tweakpane. I had an error that broke the song picker and buttons after it that took a while to find. A bigger challenge I faced was changing the shape of the visualization. I wanted to try something different then just rectangles so I replaced them with circles but drawing non-rectangle shapes is a lot more complicated because there isn't just one method you can call like fillRect(). I was not able to fill the inside of the circles I drew for some reason that I still haven't figured out but I actually like the way it looks better with just the outline of the circle so I decided to keep it that way.
