I am looking to make a LED Matrix that is 4X25 and be able to address each individual LED.
I have an Arduino Uno.
Does anyone know of a good tutorial on how to solder the matrix and maybe ideas on how to hooked them up and control them from Arduino?
Thanks for the help!
Look into playground:

From the looks of it, a MAX6953 looks like my best option. Does anyone happen to know where I can get a MAX6953 from? I looked at Mouser and there was a minimum order.
Also, if anyone knows where I can find a tutorial for it that would be amazing.
I found a good tutorial on instructables. I searched for 74hc164 (the shift register I've got).
I found it useful, hopefully you do to.

Looks like a good resource, but the max they have made was an 8X8 display.
So maybe I would have to get a couple of these chips to drive a few different LED Matrices?
Thanks for the help.
How about this - use two MAXX7219 or 7221, arrange the 64 LEDs that each can control anyway you want to.
You can request samples from MAXIM - just watch the package type you ask for.
"The MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface
microprocessors (?Ps) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays,
or 64 individual LEDs.
Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit
drivers, and an 8x8 static RAM that stores each digit. Only one external resistor is required to set the segment
current for all LEDs. The MAX7221 is compatible with SPI™, QSPI™, and MICROWIRE™, and has slewrate-
limited segment drivers to reduce EMI."
