Over the weekend, game developers Stab Yourself released Mari0, a FREE downloadable game that takes the original Super Mario Bros. and adds portals.

Umm, WHAT?!!!!!!

Check out the game trailer here below and if you’re anything like me — a Super Mario Bros. junkie — you too will hyperventilating. Seriously, I’m bugging out now. I didn’t even know Mari0 was in the works, but now that I’ve seen the gameplay, I have one thing to say: WANT!!!

I saw this Portal-themed Christmas tree in my Google+ stream posted by my friend (by way of G+) Eddie McBride.

I don’t know who the creator is, but I love it and had to share it with you all. If you’re the person made this, 1) great job! and 2) let us know who you are.

There’s a lot of great works of art out there, many of which reside in public places for all the world to see.

And while we all have much respect for said works of art, there’s not a thing wrong with wanting to geek things up a bit from time to time, so long as it’s not damaging to said works of art.

Which brings us to Astor Place in New York City’s Manhattan borough, home of the sculpture called Alamo (seen here). Sometimes also called “The Cube,” this work of art was all but begging for a geek makeover in the form of a Portal Weighted Companion Cube costume. And now it has received one, thanks to some pranksters from CalTech.

You can see the sculpture’s Portal makeover and read the note left by the pranksters below now.
