With summer in full swing, plenty of Cemetech members are keeping busy with some amazing projects. As always, make sure to check them all out and show the creators your support and encouragement:

• DYNATRIS - a Tetris clone for the HP Prime: komame showed off a slick-looking version of the classic block-dropping, line-clearing puzzle game for the HP Prime, written in Python. The game runs very well for a Python game thanks to the superior speed of the HP Prime. Check out the thread for more info and to show your support!
  
• HD Picture Viewer [C] [TI-84 Plus CE]: TheLastMillennial worked on adding 16-bit color support to this picture viewing utility for the CE family of calculators. As noted by TLM, the recent 16-bit graphics library (which won May's PotM) makes the increased colors easier to implement for this and other CE projects. Check out the latest posts in the topic to see some neat comparison images showing the power of the increased color palette! There's even a beta download if you're interested in trying it out yourself.
• Liquid Sort for the TI-84 Plus CE!: sumde2 announced a new CE game, now available in the archives! This puzzle game about sorting liquids into various vials currently has 12 levels, with instructions in the readme on how to add custom levels, so definitely give it a try if you are a CE owner.
  
• Live Base Converter CE: TheLastMillennial, along with mr womp womp, updated this useful tool to fix some bugs and minimize code size. Check it out if you are in need of a convenient way to convert between bases, right on your calculator!
• [TI-BASIC] Shades 84+ CE Port: Michael2_3B uploaded a YouTube video showcasing a recreation of his classic TI-BASIC CE game, this time in Minecraft using redstone. Watch the video if you want to see all the juicy technical details, along with a world download to try for yourself!
• Sudoku CE: Cars and Ice Cream shared another brief update, improving on the size of the stored sudoku puzzle AppVar. Be on the lookout for the first release of this Celtic CE-powered puzzle game!
• Tari's opportunistic Z80 computer: Tari posted about his recent efforts to build a custom z80 computer, using parts recycled from a point-of-sale terminal and a custom mainboard. Check out the topic for more info on this cool project using a beloved calculator CPU.
  
• Ti-Basic Practice Program: Tetris: Another Tetris clone this month, this time coming from Jeff calc 84, written in TI-BASIC for the monochrome z80 family. So far progress looks good, with basic block falling and line clearing working well, along with a list of planned features including a high score table featuring several statistics for classroom bragging rights. For more details be sure to check out the thread!
  
• Train Simulator Controller: KermMartian posted another update on his Train Simulator project, this month featuring a cardboard dashboard prototype along with a plethora of buttons, knobs, and other real train parts. If you're at all interested in trains, simulators, or hardware projects in general, check out the post, or even the extended blog post linked within!
  

That's all for July! Since Liquid Sort was our only completed project this month, it automatically wins the PotM. Come back next month for even more great project updates!
