Air Clock by Alison Pitt (2009)

This clock is designed to look like KDE 4.3's "Air" clock, but from inside Conky.

You can adjust the clock's radius and placement, as well as the size and offset of the drop shadow. You can also choose whether to display the seconds hand. This clock updates every time Conky does, so if you want to show seconds, it is recommended that you set update_interval to no more than 0.5s. If you turn off seconds, you can set the update_interval to as long as 30s. The settings are in the "Settings" section, starting at Line 21.

Call this script in Conky using the following before TEXT (assuming you save this script to ~/scripts/clock.lua):
lua_load ~/scripts/clock.lua
lua_draw_hook_pre draw_clock

Conky Widgets by londonali1010 (2009)

This script is meant to be a "shell" to hold a suite of widgets for use in Conky.

To configure:
+ Copy the widget's code block (will be framed by --(( WIDGET NAME )) and --(( END WIDGET NAME )), with "[" instead of "(") somewhere between "require 'cairo'" and "function conky_widgets()", ensuring not to paste into another widget's code block
+ To call the widget, add the following just before the last "end" of the entire script:
cr = cairo_create(cs)
NAME_OF_FUNCTION(cr, OPTIONS)
cairo_destroy(cr)
+ Replace OPTIONS with the options for your widget (should be specified in the widget's code block)

Call this script in Conky using the following before TEXT (assuming you save this script to ~/scripts/conky_widgets.lua):
lua_load ~/scripts/conky_widgets.lua
lua_draw_hook_pre widgets

Changelog:
+ v1.0 -- Original release (17.10.2009)

--[[ RING WIDGET ]]
--[[ Options (name, arg, max, bg_colour, bg_alpha, xc, yc, radius, thickness, start_angle, end_angle):
"name" is the type of stat to display; you can choose from 'cpu', 'memperc', 'fs_used_perc', 'battery_used_perc'.
"arg" is the argument to the stat type, e.g. if in Conky you would write ${cpu cpu0}, 'cpu0' would be the argument. If you would not use an argument in the Conky variable, use ''.
"max" is the maximum value of the ring. If the Conky variable outputs a percentage, use 100.
"bg_colour" is the colour of the base ring.
"bg_alpha" is the alpha value of the base ring.
"fg_colour" is the colour of the indicator part of the ring.
"fg_alpha" is the alpha value of the indicator part of the ring.
"x" and "y" are the x and y coordinates of the centre of the ring, relative to the top left corner of the Conky window.
"radius" is the radius of the ring.
"thickness" is the thickness of the ring, centred around the radius.
"start_angle" is the starting angle of the ring, in degrees, clockwise from top. Value can be either positive or negative.
"end_angle" is the ending angle of the ring, in degrees, clockwise from top. Value can be either positive or negative, but must be larger (e.g. more clockwise) than start_angle. ]]
