I'm making a scheduler for my college courses! First, it picks out the 
courses I need to take (based on what is being offered that semester) 
and stores it in an array. Then it checks the array, comparing the 
elements to all the others, and picks out classes are no more than 30 
minutes apart from each other. (That's why I've got to compare all of 
the elements.)

An example output looks like this so far:

MONDAY/WEDNESDAY: VALID COURSE COMBINATIONS
ITEC 3860 => "Software Development I" with [Dr. XYZ]  (12:0-13:45)
ITEC 3200 => "Intro to Databases" with [Dr. ABC]  (14:0-15:15)
*** OR ***
ITEC 4820 => "Info Technology Project II" with [Dr. Lil'teapot] 
(12:0-13:45)
ITEC 3200 => "Intro to Databases" with [Mr. Nodoctorate]  (14:0-15:15)

It's been a fun project to help familiarize me with Ruby!
