Bwahahahaha – I know what it is, but I can’t tell you. But you can now play a text adventure game, created by Andrew Plotkin, which will give you hints. Remember Adventure?

You really shouldn’t have wandered away from your tour guide. The gleam of glass in a deserted room caught your eye for just a moment… but with that mob of chattering tourists out of sight, the MakerBot facility doesn’t seem quite as friendly as it did a moment ago.

Servos hiss behind you — but that’s not the guidebot’s cheery mask looming out of the shadows. It’s a security bot! You’re in trouble now. You duck into the laboratory. Or is it a showroom? Test chamber? You pull the door shut; hopefully you can hide out until the robot has passed.

No maze of twisty little passages here. Just a big scary security robot. I just played it for a while – it’s awesomely fun. I expect Seth Levine and Paul Kedrosky will get sucked in this afternoon and it’ll cause Paul to need to buy a MakerBot to print out the pieces in game.

I’ll see you at CES if you are going to be there. And keep your eyes on the MakerBot site for some cool new things.

My friends at Orbotix have made a spooky Halloween video for you starring Sphero.  The costumes were made by Adam (one of Orbotix co-founders) using his MakerBot.

Happy Halloween from Sphero from GoSphero on Vimeo.

MakerBot has a great weekly TV show. This week learn about all the things you can make for halloween with your MakerBot as well as how you can help save the hermit crab. Also watch as the new MakerBot TV mascot – Mr. Maker – goes on a tour of New York City.

Before we invested in MakerBot, we bought and assembled a Thing-O-Matic. When I say we, I mean me, Jason, and Ross. It took us about 20 hours (Jason and I did the first half; Jason and Ross did the second half) and was a blast – think of it as an adult lego project. Our Thing-O-Matic has been steadily printing stuff – you can play a game of chess with our Thing-O-Matic pieces. the next time you are in my office.

As part of the endless series of Amazing Deals I bring you from my deal site, today’s offer is a fully assembled Thing-O-Matic. If you want your own 3D printer, but you don’t want to assemble it, you can buy it fully assembled for $2,500. But, through the magic of daily deals, there are 20 available for a 20% discount ($2,000). This is a one time offer from my friends at MakerBot so grab ‘em while they are available.

In additional TechStars Cloud launched today along with the first episode of TechStars on Bloomberg TV.

And finally, for all of you that have written asking for a “Convertible Debt Series” like our term sheet series, we’ve just started one on AsktheVC.com. The first post is up and introduces the series – we’ll be working through all of the terms in a convertible debt deal over the next few weeks.

Congrats and good karma to my friend Bre Pettis on being able to take his new child - Nika – home from the NICU.

Over the last few months as we were working together to close the MakerBot financing, Bre and his partner Kio Stark had Nika prematurely, which resulted in a bonus six week stay in the NICU. I talked to Bre a number of times during this period, often when he was camped out at the NICU, and he was remarkably calm and engaged during this period.

He’s written a very detailed, thoughtful, and intense post about how to survive the NICU. While I don’t have any kids, nor do Amy and I plan to, I expect all of my obsessive behavior would come out with a vengeance if I ever ended up in a similar situation to Bre’s. My guess is that his rules apply to the hospital stay of any loved one and are well worth reading.

Bre – thanks for taking the time to write up your survival guide. I’m glad everyone is home, safe, and healthy.
