# Resources

The Pen is a feature in Scratch that allows a Sprite to draw shapes, plot colored pixels, and so forth on the screen with the Pen Blocks. Lines, dots, rectangles, and circles are the easiest shapes to draw, but with enough scripting, any shape can be created.

A graphic effect is an effect that can be used on a sprite or the Stage, changing their look in some way. These blocks can be found under the Looks section. No effect, color, fisheye, whirl, pixelate, brightness, ghost, mosaic

Advanced projects using physics and math:
-Use Trigonometric principles to determine Vectors for X and Y Directions for Sprite(Object) Movement.
-Simulate Gravity Physics.
-Use Conditional Statements and While Loops (Repeat Until) to determine action within Game.
– Use Variables to store, calculate, and direct movement within Game/Simulation.
