PyBlox supports the concepts of the stage, sprites, costumes, etc. Most notably, it mimics the concurrency model of Snap! Furthermore, all NetsBlox RPCs and message passing are supported. However, PyBlox is not browser-based and neither is it lively; the program only starts up when the user runs it. Our aim with PyBlox is to ease the transition for students who want to learn a text-based language after learning programming in Snap! or NetsBlox.

The example projects files used in the demo are available on [github](https://github.com/dragazo/NetsBlox-python/tree/master/examples/projects). You can open these project in the PyBlox IDE.

But we had a problem: tiny microcontrollers such as the micro:bit lack a file system, so there is no place to store image files! Our solution was to embed the image data directly in the program as code. We will show how Snap! can be used to prepare an image for display and then compile it into a textual form of MicroBlocks code. When pasted into the MicroBlocks IDE, that textual code is converted into graphical blocks that can be run to draw the image. In addition to solving our image storage problem, this talk will show how Snap! can be used to generate code for MicroBlocks. That is, we're using a Snap! program to write a MicroBlocks program.

My 12yo daughter and I started playing NY Times Sudoku together (https://www.nytimes.com/puzzles/sudoku/hard) -- neither of us had ever really played before, I missed the early wave when everyone was playing it all the time. As we were solving hard puzzle after puzzle (but sometimes getting stuck!), we settled upon 4-5 "features" we searched for. We then wanted to see if the puzzles were getting stuck on were possible to solve based on our features (and we just weren't seeing them) or whether there were other features we needed to be looking for that we didn't know about yet. So I coded all the features in Snap! to simulate a perfect human using our features. So far (after more than a month straight), our algorithm hasn't failed to solve any puzzle. Overall, I wanted three things from this project (and all three are available in that project): (1) Prove to me that the current game can be solved. Using the URL block, it loads the current game from NY Times and then solves it interactively. (2) Let me type in what we have NOW as a partially solved game, and just show me the next hint using our algorithm. (3) What if the game were ONE slot harder -- what if we were to hide ONE of the numbers that are shown, is THAT solvable using our feature algorithm?

The game engine extension is just a demo / work in progress, but current features allow students to create powerful games: * **Camera** blocks allow the programmer to move the camera around the stage's world, beyond the usual 480x360 dimensions. Blocks allow Actors to "hold" the camera, so moving the camera around is as simple as translating, scaling and rotating existing sprites. The user can even control the camera with panning and zooming for manual actor placement and level building (see below). * **Level** saving and loading blocks capture the properties of all sprites and clones on the stage and save them to or load them from a 2d list. This allows for easier level design, without having to manually place each actor's location and other properties. * **Physics Engine** blocks allow users to turn their sprites into physics bodies that collide and have adjustable properties (mass, bounciness, velocity, etc.).

The game engine extension is just a demo / work in progress, but current features allow students to create powerful games: * **Camera** blocks allow the programmer to move the camera around the stage's world, beyond the usual 480x360 dimensions.

(using JavaScript). This is important because Snap! mostly draws lines and it's hard to draw solid shapes (especially with curves). This library allows Snap! users to include filled wedges, ellipses, and parallelograms in their projects. Unlike the raw JavaScript which uses the world coordinate system, we follow the turtle graphics model from Snap! and center the drawings on the sprite, respecting its position and rotation. Enjoy!

(DASIS) library allows students without prior programming experience to learn and explore Data Science Principles. The DASIS library brings new functionality to Snap! with support for data tables and visualization. This demo will showcase the main features of the DASIS library, including: data importation from a data file, table creation, basic table manipulation, and customizable data visualization.
