Being a vegetarian (or pescetarian, if you will), I tried my hardest to get out of dissecting frogs during biology classes. Had I been born 10 years later, I could've cut up virtual amphibians on an iPad instead.
Now, I've no idea how much those frogs cost schools, but with all the utensils and chemicals I bet it would end up costing quite a bit. iPads may be expensive, and the app will set downloaders back by $5, but they could be reused time and time again. The smell of Formaldehyde may not fill your nostrils when doing so, but the 3D graphics and wide range of tools look very realistic judging by the video of the app below. [iTunes via Recombu]
