Project teams will normally have one person who is particularly good at design, one who is particularly good at coding, and one who is particularly good at coordinating people (which probably includes coordinating writing). * Everyone will contribute to all three aspects, but I think teams are more likely to succeed if you ensure that you have all of these characteristics on your team.

Instructions

• Take a orange sheet if you want to serve as the design specialist.
• Take a purple sheet if you want to serve as the code specialist.
• Take a green sheet if you want to serve as the coordinator.
• Take a white sheet if you see another role for yourself (write down the role).
• You can take more than one sheet.

Overview

• Preliminaries.
  • Admin.
  • Upcoming Work.
  • Extra Credit.

• Time to form groups.
• A few more notes on design.
• Playing and brainstorming.

  • The rest are on the poster.

Exam Notes

I'm worried that my polygon procedures are drawing polygons at the top-left corner of the image, rather than at the center, as it shows in the examples.

Your procedures should draw the polygons wherever the turtle is. If the turtle starts in the top-left corner, then you should draw the polygon there.

In problem 2 how do I test for errors?

Look at exercise 3 in the lab on unit testing. http://www.cs.grinnell.edu/~rebelsky/Courses/CSC151/2014F/labs/rackunit-basic-lab.html

_How do I determine if a character is upper case?

char-upper-case?

How do I tell if all of the numbers in a list are even?

    (define all-even?
      (lambda (lst)
        (or (null? lst)
            (and (even? (car lst))
                 (all-even? (cdr lst))))))

    (all even? lst)
    (any even? lst) ; Don't use this for they are all even

Other Questions

Time to form groups

• Sam tries yet another somewhat unsuccessful and seemingly creative but not really approach.

A few more notes on design

• Reminder: Goal is to produce "compelling" images
  • Something people may feel compelled to continue to look at
• We achieve that by thinking about the components of an image and principles that allow us to combine those components.
• Components
  • Color (and the color palette)
  • Image plane (what we call the image)
  • Line
    • Explicit/implict
    • Straight/curved
    • Thickness, color, ...
  • Shapes
    • Geometric / Organic
      • Regular/Irregular
    • Border/boundavy vs. interior
    • Implicit shapes (positive space/negative shape)
  • Textures - patterns
    • "natural"
    • artificial
    • plus whatever GIMP does
• Relationships between elements
  • Scale (similar size/varyingn size)
  • Proximity vs. distancea
  • Repetition vs. variation

Playing and brainstorming

Options

• You may want to look at the gallery on http://mediascripting.wordpress.com.
• You may want to work on the lab.
• You must just want to search the Web for ideas.
• Revisit old labs and projects for ideas.

Things students want Sam to write or help write

• Have a turtle select things in the image

  (turtle-begin-selection! turtle)
  (turtle-end-selection! turtle OP)
  

• Do image-compute! only for part of an image.

  • Select parts of the image and use image-recompute!
• Do image-transform! only for part of an image.
  • Select parts of the image and use image-transform!

Notes from your experienced mentors

• Don't forget that you need three different techniques! Making them cohere can be an interesting challenge.
