Puerto Penasco/Rocky Point was fun, if not exactly my cup of tea… This was my first time to Mexico, so we weren’t exactly seasoned travelers, but we got by and actually had a good time.

Everything so far has relied on some tricky-to-install GUI gem… Working in SVG lets Ruby On Acid make pretty graphics (viewable in any modern browser) by outputting plain text.
Here’s a few samples. I’m sure I could produce more consistently pretty results with more SVG expertise, but that’s something I’ll have to play with another time.
Read more...A computer can mimic the style of a classical composer by analyzing sheet music. I bet GUIs could be (partially) generated for command-line tools. You just analyze how people mapped a CLI tool’s functions to a GUI wrapper (say, Git vs. GitX), then apply the rules you learn to other CLI tools.

Read more...Processing on Acid...
Got Ruby-Processing working with external libraries, so I can finally try it out with Ruby On Acid! My problem was that I couldn’t (or didn’t know how to) set the ruby load path with ruby-processing’s included “rp5” tool. But on Marc Chung’s advice, I tried loading it into vanilla JRuby (had to do a small hack, but it worked). From there I was able to set $RUBYLIB, include it from a gem, whatever.
It’s fast, too, at least compared to wxRuby on MRI 1.8.7. My dual-core MacBook can draw 3000 shapes a second without breaking a sweat.
OK, so here’s how to try it out yourself:
Save to acid_sketch.rb:
require 'rubygems'
require 'ruby-processing'

require 'rubyonacid/factories/random'
require 'rubyonacid/factories/repeat'
require 'rubyonacid/factories/sine'
require 'rubyonacid/factories/skip'

@f = create_factory
@resetter = RubyOnAcid::SkipFactory.new(0.9999)

@f.get(:red, :max => 255),
@f.get(:green, :max => 255),
@f.get(:blue, :max => 255),
@f.get(:alpha, :max => 255)
)

@f.get(:x, :max => width),
@f.get(:y, :max => height),
@f.get(:width, :max => 100),

end
end
