Script to grab one of the 10 more recent images from Unsplash, and tint and blur it for use as an iTerm background using Solarized Dark

unsplash.sh

#!/bin/bash
# NOTE: requires ImageMagick
# NOTE: will tint to the Solarized Dark default background scheme, as the iTerm background blend option didn't lower the contrast enough for me
# NOTE: Optimised for a 1280x800 point screen (my 13" Retina MBP)

set -e

index=$[ 1 + $[ RANDOM % 10 ]]
img=`curl https://unsplash.com/rss/ | xmllint --xpath '/rss/channel/item['$index']/image/url/text()' -`
curl "$img" > ~/unsplash-latest.jpg &&
