This is a fun interactive python script for your Raspberry Pi that displays different images when you turn it upside down. It has a built in menu that cycles through the image selections and a push button to exit the program. It also has a list of command line options if you want to use it on other setups or programs. Aurora is an advanced, open source application for creating animations and visual effects. It is also useful for creating screen savers. It works with Raspbian Jessie OpenCV is an open-source computer vision and machine learning software library. Using OpenCV, you can do face detection, facial recognition, license plate recognition, hit counter, find colored objects in images among other things. This software is installed using sudo apt-get install libopencv-dev python-opencv on the Pi. After installing OpenCV run the following script (playground/python/openCV_demo.py) to display the output of the video camera on your monitor using picamera. It is recommended to run the script in a python script window. If you want to use it in a different environment you will need to change the permissions of the picamera application and the video player so that it can execute. To do this navigate to Menu > Applications > Accessories >picamera and open picamera (it may ask for permissions, answer Yes), then go back into the script window and edit the file "init.py" and add or remove lines that start with #! /usr/bin/env python: When finished, save and exit picamera, then run: python3 opencv_demo. py This plays back the video camera and displays it on your monitor. If you want to save it as a file, you will need to use the command line option --capture-video-somewhere python3 opencv_demo.py --capture-video-somewhere /home/pi/recordings/me_recording.mp4 For more information on using OpenCV visit: http://docs.opencv.org/2.4/doc/tutorials/introduction/linux_installation/linux_installation.html About:A software suite to assist in the development of GUIs for Python applications. It is cross-platform and runs on Windows, macOS, and Linux (including Raspbian). Qt also runs on iOS and Android. All of this software is installed using sudo apt-get install python-qt4 python3-pyqt5 qt4-demo. This example runs a bouncing ball demo using the python module PyGame. This program will run in any Python IDE such as IDLE or Python 3 (IDLE must be installed first). After installing Python and PyGame you can run the program by going to Menu > Programming > Python 3 > IDLE (Python GUI) . Then open the file to be edited "bounce. cfa1e77820
