The script I use to backup my ffffound items. Far from perfect, and the system call is quite a hack, but I was in a hurry and this does it for me.

ffffound.rb

require 'rubygems'
require 'nokogiri'
require 'open-uri'

pages = 78
username = "fred"

def grab_url(offset)
	Nokogiri::HTML(open("http://ffffound.com/home/#{username}/found/?offset=#{offset}"))
end

def parse_document(doc)
	doc.css('.description').each do |l|
		url = "http://" + l.children[0]
		url = url.split("?")[0]
		`cd img; wget #{url}`
	end
end

for i in 0..pages
	puts "Downloading page ##{i} of ##{pages}"
	parse_document(grab_url(i * 25))
end
