Both. I'm curious to see what it's like. I organize a programming group in Berkeley (codeselfstudy.com) and would show it to them to see if people might be interested in working on algorithms problems during the meetings. I think that unusual format might make a good conversation starter in the group.
Awesome, that sounds like the perfect place to share it. Would you be willing to share the beta pages with your group and see if they have any input/feedback? I'll be sending out more pages to the mailing list soon too so they can have more than just Selection Sort to try out. Let me know (levi -at- coderscoloringbook.com) Cheers!
