This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.
You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

One of the many reasons I love working with Ruby is it has a rich vocabulary that allows you to accomplish your goals with a minimal amount of code. If there isn't a method that does exactly what you want, it's usually possible to build an elegant solution yourself.
Let's take the example of simulating the rolling of a die.
We can represent a die as an array of its faces.
die = [*?⚀..?⚅]
# => ["⚀", "⚁", "⚂", "⚃", "⚄", "⚅"]

Here are the steps needed to convert an image (like JPG or TIF) to MBTiles using GDAL:
Download and install GDAL (https://gdal.org/, https://anaconda.org/conda-forge/gdal):
conda install -c conda-forge gdal
Installing GDAL is kind of a pain in the ass, especially on Windows. I'm assuming you'll be able to work out whatever issues you run into here.
Download example jpg and tif map images we can work with:

| require 'sinatra' | |
| set server: 'thin', connections: [] | |
| get '/' do | |
| halt erb(:login) unless params[:user] | |
| erb :chat, locals: { user: params[:user].gsub(/\W/, '') } | |
| end | |
| get '/stream', provides: 'text/event-stream' do |
