+1 for the descriptive names.

Too often I see strange contractions that aren't immediately obvious, and or otherwise inconsistent naming (not just in Smalltalk), and it ruins the illusion of having a consistent whole :).

It bugs me a little ;).

It would be really cool if we could agree as a community to follow a well-defined naming scheme.

I'm rather fond of this book �

Smalltalk With Style

Any thoughts?

It's so great stuff!!! :))

Is cairo used as athens backend for this demo?
Is it should work with Bitblt backend?

In demo I see many usage of angel parameter for transformations. Do you
think about "angel unit objects" like "90 degrees" or "2 radians" instead of
raw numbers ?

there are two methods - �rotateByRadians: and rotateByDegrees:
It makes things more explicit, while if i just have
rotate: or rotateBy:, then it will be a bit ambiguous, whether
argument angle is in radians or degrees
(different frameworks assuming �different things to be default)

How #scaledBy: works with Point argument (self extend) and Float like (frame
/ 100 sin abs) at the same time? What' logic?

for uniform scale, you provide a sole number, and for non-uniform - a point,
with x and y scale factors separately.
There is a scaleX:Y: method, while scaleBy: is more for convenience.

Hello, all

I recorded a small introductory video about Athens.
Here it is:

http://vimeo.com/40653315

(about 21 minutes).

I explain some basic stuff like drawing things using Athens canvas,

building paths, use of transformation matrices etc.

Please note, this is a first video i ever recorded in such context in
my life, so don't be too harsh :)

Also, note that the animations are jagged because of video recording
frame rate, not because it is that slow in reality.

There are still a blog post pending about it.. which i plan to finish

when i will finish ;)
