Mindware has added some really great stuff to their catalog, and I've added some of them to the GalaxyGoo Toy List. Here's a sample:
Plant Lab Trio These are really cool! With these kits you grow sprouts in a non-toxic nutrient filled gel, used by NASA astronauts to grow experimental plants in space.
LEGO Mindstorms Robotics Invention System 2.0 What can I say? Other than that I've been waiting for my kids to get old enough to play with these since they were born?
Pixel Blocks If you like creating digital pixel art, you'll love pixel blocks. The blocks connect on the sides as well as when stacked, allowing interesting 3D construction possibilities, pixel by pixel.
Total Sudoku (puzzle book) A whole book of those addictive puzzles.I can't help but wonder if anyone does crossword puzzles anymore ;-)
Pinhole Camera Kit I can't remember when I first discovered pinhole cameras, but i find them fascinating. This one is on my own wish-list.
