+# StringArt
+
+The purpose of String Art is to provide the developer with practice creating a
+simple animated graphic, using geometry in the animation algorithm, and
+creating something that's visually pleasant to watch.
+
+String Art draws a single multicolored line which smoothly moves until one
+end touches a side of the enclosing window. At the point it touches a "bounce"
+effect is applied to change it's direction.
+
+A ripple effect is created by only retaining 10-20 images of the line as it 
+moves. Older images are progressively faded until they disappear.
+
+Animation libraries are not allowed. Use only Vanilla HTML/CSS/JavaScript.
+
+## User Stories
+
+-   [ ] Start by drawing a multicolored line at a random position within the
+boundary of it's enclosing window.
+-   [ ] Each 20ms draw a new copy of the line at a new position based on a
+trajectory - the incremental distance from the previous line based on the
+endpoints.
+-   [ ] When either endpoint of the line touches the boundary of the enclosing
+window change it's direction and randomly alter its angle.
+-   [ ] Progressively fade the intensity of old lines so that only the most
+recent 10-20 lines are visible to create the sense of movement or "ripple".
+
+## Bonus features
+
+-   [ ] User can specify the length of the line and it's velocity
+-   [ ] User can specify the multiple lines within the window, all
+moving along different trajectories and velocities

+## Example projects
+
+This project is very close, but has a small enclosing window and is monchromatic.

+This project is similar, but contains multiple lines and is monochromatic
