[In an animation, a man in a suit looks grumpy. Text onscreen reads, "So it's not cool when you can't play handball with your mates. But with mates like Mac's...it's way cool." 
A hand pulls a cord. 
A new screen of text appears. "At our school the kids invent 
Mac-ifications. That is... modifications to Mac's wheelchair so that THEY CAN ALL do more things." The animated man smiles. 
Hands pull down a new screen. A photo shows a boy sitting in a modified wheelchair that features a cabin with a net strung over a framework protecting the front of the cabin where Mac is sitting. 
Text reads, "Like this handball machine. All they needed was... 
1. Crazy catch. 
2. Golf umbrella holders. 
3. Some Velcro. 
And this is how they 'roll' for handball." 

A video shows a boy pushing Mac's handball machine to hit balls back to the opposing player. Mac sits inside the cabin. The ball bounces off the frame and net. Onscreen text reads, "Pretty awesome, don't you think?" The cartoon man smiles. 
Text around a photo of Mac's handball machine reads, "Just goes to show...when ALL means ALL, we make the world more ALLsome."]
