A slightly different kind of episode this week. I've decided to try a 'creativity clinic', answering listeners' questions submitted online. If you have something you'd love to know, or an area you'd like me to tackle, get in touch by email – firstname.lastname@example.org, on twitter @hackcircus, facebook hackcircuspodcast, or instagram @hackcircus. This week questions range from favourite colours to world domination. I have a lot of experience of making all sorts of different kinds of things, and if I don't know something, I probably know something who does. So send your questions in! I would love to help people out if I can. Enjoy!
