I'm at the Melbourne Maker Faire and a few cool things have caught my eye:
  1. the FreeRTOS for Arduino -- and  @fei_li_pu has persuaded me to take another look at Eclipse as an AVR development environment
  2. Cool wooden journal covers from the Beehive
  3. the MHV Arduino board
  4. Up! 3D Printer -- shame about the price and lack of Linux support though
  5. @legopoerty
  6. the Range of stuff from Freetronics. I hope they support the Raspberry Pi when it comes out
There was also lots of other cool things, steam punks, crafters, Smart Energy Group and so on. If you missed it hard luck.
