Animation artist Alisa Stern now claims to be the Doctor's current companion, and she can prove it -- they really do go everywhere together. Her Doctor is only a few inches tall and I think he's brilliant. The details and textures are perfect, and best of all it's a very good caricature likeness of dear old Eleven.
(Sometimes the Doctor Puppet has Matt Smith's goofy lopsided smile and sometimes he looks very very sad indeed... I need to know: is Alisa adding his mouth digitally in her photos? Did she make a Happy Head and a Sad Head? Is the mouth a sticker or something? Reveal your secrets, Alisa!)
