Why another answer: With anwar's answer you will not get cool update while shubham arawkar's answer is for Ubuntu 16.04 not 16.10(OP's choice). So I'm providing a solution to take care of both the issues.
The Screenlets PPA provides numerous screenlets (desktop widgets), such as RSS readers, weather, clock, countdown, a Conky-like system information widget, folder view, calendars, sensors, and much more.
Install Screenlets in Ubuntu 16.10:
sudo add-apt-repository ppa:screenlets/ppa
sudo sed -i 's/yakkety/xenial/g' /etc/apt/sources.list.d/screenlets-ubuntu-ppa-yakkety.list
sudo apt update
sudo apt install screenlets screenlets-pack-all
Done now go to dash and type
screenlets and choose whatever screenlets you want.
