Moiré scratch program

This project was created for playing with Moiré patterns in Tech Club (see the Tech News, 29 May 2007).

Moiré patterns are formed when 2 (or more) repeating designs are superimposed with slight differences in size or angle. This program is a playground for experimenting with simple Moir´ patterns.

space

to get bottom layer set up by putting the top layer into a standard location and orientation and stamping it.

right, left, up, and down

to move top layer.

a, s

to rotate top layer.

w, z

to make top layer bigger or smaller.

n

to change underlying pattern of sprite (currently dots or stripes). The dots are not quite regular, which causes some patterning even when they should be perfectly offset by 16 pixels.

t

to show just top layer

g

(default) to show both layes

b

to show just bottom layer
