GMU:Bots 'n' Plots/Apasri Titatarn

APASRI TITATARN : Bots n Plots class

First touch with Python . . . .gettin to know how to draw basic shapes

Here is my first drawing in class with coding. my sheep robot. . . funny one

My Aim about this class :

" I would like to make imageBot and furthur step would be to make it move as short animated GIF"

Homework 2nd week Assignment to make your own moving robot.

This is my CloudBot. A cloud with falling snowflakes GIF. I coded in processing with python language. Here is the code . . .

#cloud
width = 400
posx = [width/4,width/3,3*width/5,width/2,width/5,2*width/3,3.8*width/5,width/2.3]

    drawcloud(change)
    sx= width/2
    n = frameCount
    textsnow(posx,change)
  
    saveFrame("cloudbot##.jpg")

I also made the gif version of Kaleidoscope by make 35 different images each turning 10 degree of the source image.

Source image : illustration from Oliver Jeffers [[File:JEFFERS>JPG]]

This is the code of Gif Version
