Inspired byZach Holman'sspark, it brings sparklines, with greater detail, to your shell.
See the demo:
superspark is ashell script that wraps arround a tinyphp command line script. For it to run you need php 5.3 (or above) and need to place the script somewhere on your$PATH.
wget https://raw.github.com/muhqu/superspark/master/superspark \ -O /usr/local/bin/supersparkchmod +x /usr/local/bin/supersparksuperspark -h
Read values via script arguments.
$ superspark 1 2 3 5 8 15 26 ̄̄ ̄̄̄ ̄̄̄̄ ̄̄̄̄̄ ̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄
Read values fromstdin. One value per line.

One value per line. SleepN seconds between redraws.
$ superspark -n 1 -c"seq 0 40 | awk '{ printf\"%6d\\n\", (sin((systime()+\$1)/2)*cos((systime()+\$1)/4)+1)*20; }'" ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄ ̄̄̄̄ ̄̄̄̄ ̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄ ̄̄̄̄̄ ̄̄̄̄ ̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄ ̄̄̄̄ ̄̄̄̄ ̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄ ̄̄̄̄ ̄̄̄̄̄ ̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄ ̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄̄
Continuously read fromstdin and draw an accumulated graph with every new value. One value per line.

The sparklines are assembled using the unicodecombining characterU+0304 which is namedCOMBINING MACRON. ...like an apostrophe dash. So, this obviously only works on full-fledged UTF-8 enabled terminals... e.g.iTerm 2, Terminal.app on Mac. Don't know about windows/linux support yet...
