These are 3 conky setups I use frequently. All of them make use of two little apps I wrote called fluxtwitter and fluxweather, to get weather and twitter timeline, and gcalcli to access google calendar. The on-desktop terminal is tilda.
conky-yell - based on another one I found on the net, I can't remember where... I liked the big design date, and added a couple of more info...
conky-oneliner - a one-line conky setup, also adapted from another one I found on the net.
