When the Scout Report covered Froguts.com in February 2002, this amazing virtual frog dissection was available for free. Unfortunately, that's no longer the case. However, Froguts.com has added more of these extraordinary simulations, and free demos are available the frog, squid, and owl pellet. The squid demo covers external structures only, and follows a self-quizzing format. The frog dissection demo goes a bit further, but the owl pellet demo is little more than a puzzle game (although the reconstructed mouse does do a freakish, vibrating dance at the end). Demos are in development for the remaining dissections: fetal pig, rat, cow eye, starfish, earthworm, perch, and crayfish.
