You already know about reactive data sources. Views can be made reactive as well. Technically speaking, we make the view a reactive data source by storing it in the database and observing changes.

Create a new app.
Delete the default html, js, and css.
Put the code below into a js file and run meteor.
Then use the console to change either the View "html" property or the Number "val" property. (see code for examples)
Try inserting and updating your own views and numbers.

N.B. The code is not an example of best practice, just a proof of concept. It relies on functions that are included in the Meteor Handlebars package. These functions could change or be removed in the future.

	max, vol, memo = 0, 0, 0
	[2, 5, 1, 3, 1, 2, 1, 7, 7, 6].each do \|n\|
	if n > max
	max = n
	vol += memo
	memo = 0
	else
	memo += max - n
	end
	end

	user nginx;
	worker_processes 1;

	error_log /var/log/nginx/error.log warn;
	pid /var/run/nginx.pid;

	events {
	worker_connections 1024;
	}

	This assumes you've already set up your instance with node, npm, forever, mongodb, configured ports, and have optionally added a web server like nginx to proxy access to meteor.
