Jurassic Park Computers were Weaker than your cell phone

The movie Jurassic Park was created using computers thar ran at 133 MHz. Total. That is less computing power than your phone. Orders of magnitude less. A $400 phone runs with dual 2.0 Ghz and six 1.7 Ghz (six!) processors. The silicon graphics computers that were used to create that movie cost $80,000 at the time, with even more than that in cost for software. A $130 raspberry pi has more raw processing power.

You can kludge away using your phone as a bodgy solution.

If you are interested in drawing, then draw on your phone and see what you can make. Bodge a solution.

Then you will know whether the 10x upgrade is worth it.
