If you use a scientific calculator, this application created by XDA member mpscuba68 will be of your interest. Ported from the HP48gx calculator, this emulator will give you that great old calculator look you used in the past on your Windows Mobile screen.
The developer tested this emulator on the HTC Leo but should work on other devices running WM 2003 and up.
To use it just copy the cab to your SD card and install to main memory, Run Emu48 and change the KLM Script to: Realistic HP48GX [WVGA].

HP48gx for the HTC HD2
Requirements: touch screen
Overview: All-new emulator of the 38/39/40/48/49 that runs on Pocket PC 2002, Windows Mobile 2003, 5.0, 6.0, and 6.5 Professional (ARM Platform). Includes a WVGA bitmap (480*800) and script for the 48GX, other scripts can be implemented. Rom 48g included. Based on Emu48 1.50 for Windows.
More Info: This is my spes cab for the HD2, I do not take any credit for it (that goes to Sébastien Carlier and Christoph Gießelink http://hp.giesselink.com/emu48.htm), I extracted the necessary files and repacked those from different exe/cab files, and have it working on my HTC HD2. It should work on all wm’s and can be modified by adding different KLM scrips for different screen resolutions, you will find those at http://www.hpcalc.org.
Download from: http://www.divshare.com/download/12290837-3cc and copy the cab to your sd card and install to main memory.
Run Emu48 and change the KLM Script to: Realistic HP48GX [WVGA]
The result should be as my screen shot.
