- Subzero still working on finishing and optimizing Quadrilaterals
- Primary cause of slowness in Quadrilaterals, constant redrawing of line segment in 290-296
- problems w/ current Quadrilaterals activity
- u have absolute and not relative positions in css, this could cause problems going b/w different machines
- not using regular DOM elements for buttons -- but this is easy to fix and u can just do it on the next activity
