Having read comics a lot as a kid I always dreamed of having a mutation. Having my genetic material altered so that I could fly or turn invisible would have been great. However, as I grew up I realized that mutations often lead to things like health problems and considered myself better off.
Now watching this video, I may have to reconsider. According to the person who posted it on YouTube it was taken in Russia. It appears to show a humanoid creature crawling across the exterior of an apartment building.
