Opencv provides are useful, but limited, method of building a GUI. A much more complete system could be acheived using pyqt. The question is, how do we display images. There are quite a few possible routes but perhaps the easiest is to use QLabel since it has a setPixmap function. Below is some code that creates two labels. It then creates a grey pixmap and displays it one of the labels. code: staticLabel1.py

from PyQt5.QtWidgets import QWidget, QApplication, QLabel, QVBoxLayout
from PyQt5.QtGui import QPixmap, QColor
import sys

	#!/usr/bin/env bash

	# Applies common security measures for Ubuntu servers. Run it before doing the inital deploy with basecamp/kamal
	#
	# Afterwards, you'll only be able to SSH into the server as 'nonroot', eg. [email protected]
	#
	# So add this to your Kamal deploy.yml:
	# ```
	# ssh:
	# user: nonroot

	// Package main is a sample macOS-app-bundling program to demonstrate how to
	// automate the process described in this tutorial:
	//
	// https://medium.com/@mattholt/packaging-a-go-application-for-macos-f7084b00f6b5
	//
	// Bundling the .app is the first thing it does, and creating the DMG is the
	// second. Making the DMG is optional, and is only done if you provide
	// the template DMG file, which you have to create beforehand.
	//
	// Example use:

	# .github/workflows/app.yaml
	name: My Python Project
	on: push
