Preliminaries

Admin

• For those of you who have not dealt with preregistration at Grinnell before, you can still enroll in a class that says it has no slots available.
  • We let classes overenroll and then we hack away at them. Isn't that a great approach?
• This Friday we will be moving our class to ARH 302 (3rd floor lecture hall) to hear Hilary Mason '00. Class starts at 12:45.
  
  • We won't have a quiz this week.
• Grading:
  • Homework is reduced to 5% of your grade. The other 5% goes to the best of homework/quizzes/labs.
  • I will see how much I can grade through this coming weekend (which is the next reasonable chunk of free time I have).
    
    • Default grade on ungraded work is "check".
    • After you get the grades back, you can request that I grade any ungraded assignment.
    • Note that I need to grade both classes, and I do have to do class prep and things other than work.
• Today in class we will watch Sam engage in "Deck Wars" (no, not the TV show version; the Powerpoint version).
• Upcoming extra credit opportunities:
  • Town Hall, Wednesday, November 13, noon or 7:30 p.m.
  • Learning from Alumni, Thursday, 2:15: Atul Gupta, Trustee
  • CS Extra, Thursday, 4:30: Hilary Mason '00
  • Informal chat with Hilary Mason, 8-9 pm
  • NO CS TABLE FRIDAY!
  • Career Connections with Hilary Mason '00, CLS, Friday, 4:15-6:30 (I don't know how Career Connections work; I expect it's really 4:15-5:00)
  • Swim meet Saturday, noon; Beth swims at 3pm.
  • Football, Saturday, noon (TJ and Jake are lots of fun to watch)
  • Basketball, Friday and Sunday
  • Digital Commons talk Monday, November 18, 7:00 p.m. or so
  • CS Talk, Lunch, Wednesday, November 20 (info forthcoming)
  • Hamlet, some time soon.
  • "Data Sovereignty: The Challenge of Geolocating Data in the Cloud", November 25, 4:15 JRC 101
  • Showing of "Gold Fever" by Andrew Shurburne '01 or so, 7:00 p.m. Monday, November 25, ARH 302
  • Tuesday, November 20, 4:15 p.m., JRC 209 a gaming event with the game [d0x3d!]

Questions on HW8

It's hard.

How do we have a counter

(define counter (vector 0))
(define increment-counter!
  (lambda ()
    (vector-set! counter 0 (+ 1 (vector-ref counter 0)))))
(define get-counter
  (lambda ()
    (vector-ref counter 0)))
(define reset-counter!
  (lambda ()
    (vector-set! counter 0 0)))

Chike says that output doesn't always look like what you think it will, so check the car and the cdr. Scheme prints trees badly.

Background: About the project

• Tie together ideas from the semester
• And apply to apply them to the "image making" domain
• Write a procedure (image-series n width height)
  • Output: "Interesting image" of given width and height
  • Same n: Same image, just scaled differently
    • Some things are nearly impossible to scale, such as brushes
  • Different n: Different images (for natural n in the range 0 ... 999, inclusive)

• Well documented (internal)

• Additional things

  • NO RANDOMNESS
  • Proposal next week with sketches
  • Use multiple techniques
  • It is up to you whether you use other imagegs and whether that meets legal expectations. BUT CITE

What makes an image "interesting"?

• Keeps the viewer engaged (or some viewers engaged) - "Why did the artist do this?"
• Relationships
  • Between the components of your image
  • To other images in your series
  • To other works of art
  • To the world beyond
• Knowing design issues that you can take advantage of

General elements of design

• Color
• Line - size, color, thickness, straightness, etc.
• Shapes - Coherent units of your image, sometimes from lines, sometimes from color differences.
  • Geometric shapes
    • Regular
    • Irregular
  • Organic
  • Positive shape / negative shape
• Texture
  • Natural
  • Unnatural

Relationships between elements

Broader design principles
