The Stabyourself folks have created a brilliant Mario/Portal mashup as free/open software for Linux/Mac/Windows. Check out the trailer and be amazed, then play the game and watch your free time vanish!

Two genre defining games from completely different eras: Nintendo's Super Mario Bros. and Valve's Portal. These two games managed to give Platformers and First-Person Puzzle Games a solid place in the video game world. But what if Nintendo teamed up with Valve and recreated the famous Mario game with Portal gun mechanics?

A complete from scratch recreation of Super Mario Bros. with a focus on perfectly imitating the feel the 1985 classic gave us. Then give Mario a portal gun, add puzzle game mechanics from Portal and there you go. And if that wasn't crazy enough, play 4-player coop, with everyone having their own Portal gun!

About Mari0

A trio of Ur-nerds have recreated the Game Boy's Super Mario Land using Minecraft. They laid 18 million blocks to accomplish the feat. It took 500 hours.

Each image is a masterpiece in block placement, dropping dyed wool blocks in the game's creative mode within the frame of a massive Game Boy created in the virtual world. The Game Boy's screen is 160 blocks across and 144 blocks tall. That means it takes 23,040 blocks to fill the screen, each representing a single pixel in the game.

James Wright, a 21-year-old British carpenter who lives in England, and Joe Ciappa, an unemployed 29-year-old living in the U.S...

About that time another player, 29-year-old Tempusmori, who lives in the Netherlands, had the idea to make a full-sized, 1:1 Game Boy in Minecraft.

"The Game Boy allowed us to pretty much recreate any original Game Boy game," he said...

"What you see is 100 percent Minecraft," Wright said. "Every pixel on the screen is one wool block. The screen itself is on a giant Game Boy. We build each screen take a screenshot from above. After the picture we move everything that needs moving for the next screen and repeat."
