Datapoint later decided not to use the chip, and Intel marketed it as the 8008 in April, 1972. This was the world's first 8-bit microprocessor. It was the basis for the famous Mark-8 computer kit advertised in the magazine Radio-Electronics in 1974. Source(s): http://en.wikipedia.org/wiki/Microproces...
In the photo in the middle, we see a mother opossum with babies down a wall. She actually can climb up and out. They are really good climbers. When I go into an attic to look for opossums, I usually look down all the available walls, and that's where I find them. That was the case in the right photo.
Wall-Jumping is a technique used in Scratch to make sprites bounce off walls. This allows a character in a project, for instance, to scale up massive heights of walls rather than jumping on individualized sections like stairs. It is commonly used in platformers. This is just one of the ways for wall jumping to work.
