As a Smalltalk evangelist, I use every tool at my disposal to draw public attention to Smalltalk. They use pretty models at car shows, and even technology shows. Unless you are steeped in Political Correctness, using images of pretty women is fair game.
Moreover, I used this opportunity to play off the name Amber. (You do know who is in the picture, right?) Fans of Zombieland and Machete Kills will appreciate the humour.
