Needless to say that I was very thrilled to have the chance to meet Brian at the conference. He has been a great source of inspiration for me (and for others I am sure!) : his website is one of my go to website when I am looking for ideas and inspiration! Go check it out! Thanks @mraspinall!
Have fun being curious!
